Add INHERITED declarations to class declarations that prevent
compilation with the flag.
Remove SK_DEFINE_INST_COUNT from all class implementations. Instead,
use function-local static variables in the reference count helper
classes to create the global instances to store the needed info. The
accessor functions are defined inline in the helper classes, so
definitions are not needed. The initialization point of the variables
should be as well defined as previously.
Remove SK_DECLARE_INST_COUNT_TEMPLATE and use SK_DECLARE_INST_COUNT
instead. This avoids possible future compilation errors further.
For SK_ENABLE_INST_COUNT=0 compilation, add an empty static member
function to all classes that use SK_DECLARE_INST_COUNT and
SK_DECLARE_INST_COUNT_ROOT macros. The function ensures that classes
contain public INHERITED typedef. This member function seems to be
compiled away. This shouĺd ensure that part of the compilation errors
are caught earlier.
Also adds DSK_DECLARE_INST_COUNT to few SkPDFDict subclasses.

Make the decision to convert thin, non-hairline paths to hairline
paths at the renderer level.
The current nv_path_rendering implementation does not render
hairlines. Rendering the hairlines with normal renderers cause
unneccessary gl program changes, which is quite slow.
Changes the behavior of non-nv_path_rendering paths to always perform
the optimization if the shape ends up being painted by a renderer that
wants the optimization. Previously the optimization was applied only
when callgraph started with SkCanvas::drawPath.
Applies the optimization for GrAAHairLineRenderer and
GrDefaultPathRenderer.
This changes gm results for dashing3_{msaa4,gpu} and drawlooper_msaa4.

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.

Adds requiresVertexShader to GrGLEffect and updates the necessary
effects to override it and return true. Also reworks GrGLProgram

at the beginning, and determines if it needs a vertex shader before

Adds a nested class to GrGLShaderBuilder called VertexBuilder. Now
GrGLShaderBuilder can only modify the fragment shader directly. In
order to modify the vertex shader, the client code needs to call
getVertexShader, which will return null for vertex-less shaders.

The Ubuntu-x86 compiler was optimizing out a case where I was
reseting the isStroked boolean based on the new inner radii.
This changes it to check the radii at the time the effect is
created, which tricks the compiler into doing the right thing.

Clamp square of gradiant length to non-zero value so it can be passed to
inversesqrt().
Also adds some fixes to rrect setup to avoid crossing zero.
Skia issue #1372

This uses the standard ellipse equation as a signed distance
test, and adjusts the result by the length of the gradient
at that point to get a better approximation of the distance
to the ellipse. It replaces the standard ellipse and
roundrect shader renderers.
Also adds a check to see if the curvature extrema of the
stroke are less than the curvature extrema of the ellipse (i.e.
the radius of curvature is larger). In this case, it's no
longer an ellipse and we can't use this renderer.
Only supports stroking for near-circular ellipses.

Due to floating point precision errors, using the formula b^2x^2 + a^2y^2 - a^2b^2
doesn't work on the Nexus 10 GPU. Changed to use x^2/a^2 + y^2/b^2 - 1.
Addresses issue 1290.

Also remove GrPaint from a number of methods -- we only
use it to get the AA state.

This uses the OvalRenderer to render roundrects as "stretched ovals." It adds an
additional shader that handles the straight edges of ellipsoid roundrects better,
and uses the circle shader for roundrects where the two radii are the same. Only
axis-aligned, simple roundrects are supported. Handles fill, stroke and hairline.
