17035b0211a3c9d45ea46a99217a6acbe76e8fbe 03-Sep-2014 John Reck <jreck@google.com> Have destroy call freePrefetchedLayers

Bug: 17208461

There's a potential race condition between HardwareRenderer.destroy()
being called (which calls destroyCanvasAndSurface()) and the renderer
being finalized (which is what calls freePrefetchedLayers), during which
time it's possible we get a TRIM_MEMORY_COMPLETE and destroy the EGL
context.

Fix this race condition by moving stopDrawing() and freePrefetchedLayers()
into destroyCanvasAndSurface() where they should have been in the first
place.

Also, if we hit the assertion failure, dump the current state of
Caches to try and provide more context for the failure.

Bug #7146141

This new cache is used in a similar way to LayerCache. It helps
reuse already allocated stencil buffers and thus avoid churning
memory on every frame.

Bug #7146141

This change moves the resizeLayer() from LayerCache (where it should
never have been anyway) to Layer. This makes a little more sense.

Fonts are now described by a transform matrix. This lead to switching
from a vector to a hashmap. This change therefore adds new comparators
and hash computations to Font.

Bug #3413433

This change will be beneficial to Launcher to avoid hiccups when
swiping pages of icons. When a layer is discarded, it is kept
in the layers pool instead of being destroyed right away. This
favors memory reuse over allocations.

This change also adds a new memory usage flag. When turned on, the
following is printed after every frame:

This should help tracking possibe memory issues.

This optimization is currently disabled until Launcher is
modified to take advantage of it. The optimization can be
enabled by turning on RENDER_LAYERS_AS_REGIONS in the

This change removes the need for the SortedList and instead just
add a generated id to each FBO stored in the cache. This is an
artificial way to store several FBOs with the same dimensions.

This change introduces a new generational cache called GenerationMultiCache
that can store several values with the same key. This can be used to use
multiple layers of the same size at the same time, without recreating them
over and over again.

The cache is used to draw layers so that a new
texture does not have to be recreated every time
a call to saveLayer() happens.

The FBO cache used a KeyedVector, which is a bad
idea. The cache should be able to store several
FBOs of the same size (this happens a lot during
scrolling with fading edges for instance.) This
will be changed in a future CL.
