Use fixed function pipeline only when drawing paths. Previously FF
vertex shader was used when drawing normal geometry if path rendering
was enabled.

This is required to make Chromium integration easier. This way
fixed function vertex shading, including vertexshader-less programs,
need not be implemented in the Chromium command buffer.

Removes FF TexGen functionality, as it is not used anymore. Likewise
removes the fixedFunctionSupport GL capability flag.

This fixes the corruption in the NVPR images here:
http://108.170.217.252:10117/builders/Test-Win8-ShuttleA-GTX660-x86-Debug/builds/251/steps/CompareGMs/logs/stdio

caused by:

https://skia.googlesource.com/skia.git/+/65ee5f424cb4dabd453268902c00086605d77c1d

The stencil path step writes inside and outside the clip when the clip is implemented by
a coverage effect. The path cover step then doesn't write outside of the clip because the FS
discards. This leaves stencil values outside of the clip non-zero which messed up subsequent
path or clip draws to those samples.

a34995e18b1f0a7d8c9f23451718bb30ff0105b0 23-Oct-2013 commit-bot@chromium.org <commit-bot@chromium.org@2bbb7eff-a529-9590-31e7-b0007b416f81> Implement SkColorFilter as a GrGLEffect

Adds GrEffect::willUseInputColor() which indicates whether or not the
input color affects the output of the effect. This is needed for
certain Xfermodes, such as kSrc_Mode. For these modes the color filter
will not use the input color.

An effect with GrEffect::willUseInputColor() true will cause all color
or coverage effects before it to be discarded, as their computations
cannot affect the output. In these cases program is marked as having
white input color.

This fixes an assert when Skia is compiled in a mode that prefers
using uniforms instead of attributes for constants. (Flags
GR_GL_USE_NV_PATH_RENDERING or GR_GL_NO_CONSTANT_ATTRIBUTES). Using
attributes hides the problem where the fragment shader does not need
input color for color filters that ignore DST part of the filter. The
assert would be hit when uniform manager tries to bind an uniform which
has been optimized away by the shader compiler.

Adds specific GrGLSLExpr4 and GrGLSLExpr1 classes. This way the GLSL
expressions like "(v - src.a)" can remain somewhat readable in form of
"(v - src.a())". The GrGLSLExpr<typename> template implements the
generic functionality, GrGLSLExprX is the specialization that exposes
the type-safe interface to this functionality.

Also adds operators so that GLSL binary operators of the form
"(float * vecX)" can be expressed in C++. Before only the equivalent
"(vecX * float)" was possible. This reverts the common blending
calculations to more conventional order, such as "(1-a) * c" instead of
"c * (1-a)".

Changes GrGLSLExpr1::OnesStr from 1 to 1.0 in order to preserve the
color filter blending formula string the same (with the exception of
variable name change).

Shaders change in case of input color being needed:
- vec4 filteredColor;
- filteredColor = (((1.0 - uFilterColor.a) * output_Stage0) + uFilterColor);
- fsColorOut = filteredColor;
+ vec4 output_Stage1;
+ { // Stage 1: ModeColorFilterEffect
+ output_Stage1 = (((1.0 - uFilterColor_Stage1.a) * output_Stage0) + uFilterColor_Stage1);
+ }
+ fsColorOut = output_Stage1;

Shaders change in case of input color being not needed:
-uniform vec4 uFilterColor;
-in vec4 vColor;
+uniform vec4 uFilterColor_Stage0;
out vec4 fsColorOut;
void main() {
- vec4 filteredColor;
- filteredColor = uFilterColor;
- fsColorOut = filteredColor;
+ vec4 output_Stage0;
+ { // Stage 0: ModeColorFilterEffect
+ output_Stage0 = uFilterColor_Stage0;
+ }
+ fsColorOut = output_Stage0;
}

Express (GLSL expression, possibly known value) pairs as a class
instead of two variables Introduces GrGLSLExpr<N> to encapsulate
the expression and possibly constant-folded value of the expression.

This simplifies passing of the expressions to functions.

Changes the shaders with following patterns:
{ // Stage 0: Linear Gradient
vec4 colorTemp = mix(uGradientStartColor_Stage0, uGradientEndColor_Stage0, clamp(vMatrixCoord_Stage0.x, 0.0, 1
colorTemp.rgb *= colorTemp.a;
- output_Stage0 = vec4((vColor) * (colorTemp));
+ output_Stage0 = (vColor * colorTemp);
+ }

Previously the vector cast was always added if constant folding was
effective, regardless of the term dimensions. Now the vector upcast is
not inserted in places where it is not needed, ie. when the binary
operator term is of the target dimension.

Also, some parentheses can be omitted. It is assumed that
GrGLSLExpr<N>("string") constructors construct a simple expression or
parenthesized expression.

Otherwise the shader code remains identical.

Removes the VertexBuilder nested class from GrGLShaderBuilder in favor
of a new GrGLFullShaderBuilder subclass, and adds an optional emitCode
overload to GrGLEffect that takes a GrGLFullShaderBuilder. Makes
setData virtual in GrGLEffectArray and adds a GrGLVertexEffectArray
subclass that gets built using a GrGLFullShaderBuilder. Also adds a
new GrGLVertexEffect subclass that makes the GrGLFullShaderBuilder
overload required for emitCode, and updates GrGLEffects to inherit
from GrGLVertexEffect where needed.
