I guess we don't want to overwrite the last line in every RGBA glyph
with our one-line texture atlas spacer?

1e546815bbb736c50679a8aefc25f48561026fc5 25-Jun-2013 Victoria Lease <violets@google.com> Support RGBA fonts and bitmap fonts (and RGBA bitmap fonts)

Quite a few things going on in this commit:

- Enable bitmap strikes by default in Paint objects.

The SkPaint parameter that enables bitmap strikes was not previously
included in DEFAULT_PAINT_FLAGS. This effectively disabled bitmap
fonts. Oops! It's for the best, though, as additional work was needed
in Skia to make bitmap fonts work anyway.

- Complain if TEXTURE_BORDER_SIZE is not 1.

Our glyph cache code does not currently handle any value other than 1
here, including zero. I've added a little C preprocessor check to
prevent future engineers (including especially future-me) from
thinking that they can change this value without updating the related
code.

- Add GL_RGBA support to hwui's FontRenderer and friends

This also happened to involve some refactoring for convenience and
cleanliness.

Draw Operation merging
527a3aace1dd72432c2e0472a570e030ad04bf16 04-Mar-2013 Chris Craik <ccraik@google.com> Draw Operation merging

Merge simple bitmap draw operations and text operations to avoid
issuing individual gl draws for each operation. Merging other ops to
be done eventually.

The methods are different - the bitmap merging generates a single
mesh for reused, unclipped images (esp. repeated images in a listview)

The text approach queries just defers the normal font rendering until
the last drawText in the sequence that can share the same shader.

Patches are sorted and merged, but don't yet have a multiDraw
implementation. For now, the pretending-to-merge gives better sorting
behavior by keeping similar patches together.

cf51a4199835e9604aa4c8b3854306f8fbabbf33 09-Apr-2013 Romain Guy <romainguy@google.com> Introduce PixelBuffer API to enable PBOs

PBOs (Pixel Buffer Objects) can be used on OpenGL ES 3.0 to perform
asynchronous texture uploads to free up the CPU. This change does not
enable the use of PBOs unless a specific property is set (Adreno drivers
have issues with PBOs at the moment, Mali drivers work just fine.)

This change also cleans up Font/FontRenderer a little bit and improves
performance of drop shadows generations by using memcpy() instead of
a manual byte-by-byte copy.

On GL ES 2.0 devices, or when PBOs are disabled, a PixelBuffer instance
behaves like a simple byte array. The extra APIs introduced for PBOs
(map/unmap and bind/unbind) are pretty much no-ops for CPU pixel
buffers and won't introduce any significant overhead.

This change also fixes a bug with text drop shadows: if the drop
shadow is larger than the max texture size, the renderer would leave
the GL context in a bad state and generate 0x501 errors. This change
simply skips drop shadows if they are too large.

First OpenGL ES 3.0 based optimization
0908764b2b3cf5075df4178a5f0a8547dcb7b317 04-Apr-2013 Romain Guy <romainguy@google.com> First OpenGL ES 3.0 based optimization

This change uses a new OpenGL ES 3.0 feature to upload less data when
the font cache needs to be update. This can result in significant
performance improvements on device with large textures or with locales
that use a lot of glyphs (CJK for instance.)

This change also fixes various unpack alignment issues. The unpack
alignment, as well as the unpack row length, is not texture specific
but a global state that affect all glTex/SubImage2D calls. Some of
them were missing the appropriate glPixelStorei() call. This could
result in corrupted textures.

SystemServer is currently a monolithic class that brings up key system
services. This change is the first phase of refactoring it to be more
configurable. Specifically, it adds a set of on/off switches used to control
startup of individual services. Future plans include finer grained controls
and a more explicit and consistent startup sequence for these services.

If a perspective transform is set on the Canvas, drawText() should
not attempt to rasterize glyphs in screen space. This change uses
the old behavior instead (i.e. rasterize the glyphs at the native
font size and apply the transform on the resulting mesh.)

This change also adds an optimization: empty glyphs (spaces) do
not generate vertices anymore. This saves a lot of vertices in text
heavy applications such as Gmail.

7bb3cfe1cca4016ce95d3ef059761f4bb2d668bb 15-Nov-2012 Sangkyu Lee <geteuid@gmail.com> Another optimization of glyph cache uploads

Previously, cache textures were updated whenever mCurrentCacheTexuture was changed.
Since updating cache textures needs glTexSubImage2D call, frequent changing
of mCurrentCacheTexture (which can easily happen when an app uses lots of unique glyphs
even with precaching) caused many glTexSubImage2D calls and bad framerates.
This patch optimized isssueDrawCommand function. Consequently, changing mCurrentCacheTexture doesn't
cause glTexSubImage2D call any more and it will improve font rendering performance.

Only upload the changed area of the glyph cache, not the entire
bitmap. Note that we can't do the full-on optimization here of copying a sub-rect
of the bitmap because of GL ES 2 limitations, but we can at least copy the
horizontal stripe containing the dirty rect, which can still be a big
savings over uploading the entire bitmap.

It is unlikely, but possible, to draw so many glyphs in a frame
(especially of the glyphs are quite large) that the cache starts flushing
itself to fit the later glyphs in. This causes unnecessary thrashing, because
when we actually draw the frame, we will again need to flush to fit the
earlier glyphs in, and then flush again to fit the later ones in.

It is better to avoid thrashing the cache at the precache phase, and wait
until we actually draw the glyphs that do not fit to do any eviction of
the earlier glyphs.

This change simply notes when we are in the preaching phase, and avoids flushing
the cache when a glyph does not fit.

378e919ccb75efe24d5a5aa75ac2c6ef255dcb48 16-Aug-2012 Chet Haase <chet@google.com> Remove CacheTextureLine structure from FontRenderer

CacheTextureLine was useful before we were packing the glyph
textures; it allowed simple packing of any particular texture according to
how many lines there were in a texture, and how tall those lines were.
Now that we are packing more efficiently (both horizontally and vertically
in any given texture line), it is more efficient to have
open space in every texture, removing the need for CacheTextureLine (which
now gets in the way since it limits how much can be stored in each line).

This change removes CacheTextureLine and just uses CacheTexture directly,
allowing caching of glyphs anywhere in the open space of each texture. As before,
the packing of these glyphs is determined by the CacheBlock structure, which
is a linked list of open spaces in each CacheTexture.

the multiple-upload issue of caching at render time.

e816baea651476aca4407200d4a5e629b9ab8dfa 09-Aug-2012 Chet Haase <chet@google.com> Optimize interactions with glyph cache

There are two fixes here:
- precaching: instead of caching-then-drawing whenever there is a new
glyph, we cache at DisplayList record time. Then when we finally draw that
DisplayList, we just upload the affected texture(s) once, instead of once
per change. This is a huge savings in upload time, especially when there are
larger glyphs being used by the app.
- packing: Previously, glyphs would line up horizontally on each cache line, leaving
potentially tons of space vertically, especially when smaller glyphs got put into cache
lines intended for large glyphs (which can happen when an app uses lots of unique
glyphs, a common case with, for example, chinese/japanese/korean languages). The new
approach packs glyphs vertically as well as horizontally to use the space more efficiently
and provide space for more glyphs in these situations.

Bug #6942209

The font renderer was preserving a 1 px border around each glyph to ensure
bilinear filtering would work nicely. Unfortunately, this border was not
set to 0 when glyphs were added in the cache to replace old evicted glyphs.

416a847633680d94efb926837efdc18726d54918 20-Jul-2012 Raph Levien <raph@google.com> Add drop shadow for drawPosText in hwui renderer.

This patch adds support for drop shadows (setShadowLayer) for
drawPosText in the hwui renderer. In and of itself, it's not very
important, but it's on the critical path for correct mark positioning,
tracked as bug 5443796.

The change itself is fairly straightforward - it basically just adds an
extra "positions" argument to all draw and measure methods on the code
path for drawing drop shadowed text, as well as to the cache key for
cached shadow textures.

Bug #6597730

Text would sometimes not appear when rendered with textured content
(BitmapShader, LinearGradientShader, etc.) This was due to a misuse
of OpenGL texture unit in FontRenderer. Textured text normally uses
two texture units:
- texture unit 0 for the font cache
- texture unit 1 for the textured content (gradient, etc.)

Recent changes to the font renderer allow it to bind new textures
while processing the text's geometry (this happens when caches get
full or when switching font size for instance.) The bindings were
done without ensuring the texture unit was the correct one
(unit 0), thus replacing the content of another texture unit
(unit 1).

This lead to text being drawn using the font cache itself as the
content texture, making the text invisible.

Bug #6408362

FontRenderer allocates large font textures when more room is needed
to store all the glyphs used by an application. Thse large textures
are the first to be freed when memory needs to be reclaimed by the
system. When freeing a texture, the renderer would however not set
the texture name to an invalid name, leading future allocations to
be performed on the same texture name. That name could have by then
be recycled by the driver and returned by a call to glGenTexture
and used to create an entirely different texture. This would cause
the font renderer to point to the wrong texture, thus leading to
the "corruptions."

Bug #6196903

Whenever a memory flush happens, the GL renderer discards some or all of its
font caches. Each font cache holds an array of vertex indices that was
initially designed to have the same life cycle as the process. This changed
when memory flushes were introduced but this array was never taken care of
in the destructor.

Currently, font renderers eliminate some texture caches when
memory is trimmed. This change makes it go further by eliminating the
large-glyph caches for all font renderers. These caches are
only allocated as needed, but continue to consume large amounts of
memory (CPU and GPU) after that allocation. De-allocating this memory
on a trim operation should prevent background apps from holding onto
this memory in the possible case that they have allocated it by drawing
large glyphs.

There were 2 issues remaining after a recent change to support
glyph caching from multiple textures:
- memory in the GPU for all textures was being allocated automatically.
This is now lazy, being allocated only when those textures are first
needed.
- filtering (applied when a rendered object is transformed) was ignoring
the new multiple-texture structure. Filtering should be applied correctly
whenever we change textures.

Some GPU architectures could not handle the previous implementation

and eventually a crash due to these memory issues. The solution is to move to
a system of several, smaller caches instead of one monolythic cache for all
glyphs.

When an app tries to render a bitmap or path larger than the GPU's maximum
texture size, the drawing command is ignored and a warning is logged. This
change also makes texture drawing more robust by catching potential errors
during texture creation.

This change also fixes a crash in the FontRenderer. The destructor would
sometimes try to free an uninitialized array.

This changes binds all textures to GL_TEXTURE0, this will have
to be changed when combining shader capabilities.

The generator supports features that are not yet implement in the
renderer: color matrix, lighting, porterduff color blending and
composite shaders.

This change also adds support for repeated/mirrored non-power of 2
bitmap shaders.
