* Always create an instance when testing GrEffects for SkXfermode and ↵Gravatar commit-bot@chromium.org2013-10-24
| | | | | | | | | | | | | | | | | | SkArithmeticMode Previously the TestCreate methods of the effects would create a static instance and return that for all invocations. This is probably a copy-paste error going back to initial TestCreate method in r8449. At that time, the effect was always the same and thus static usage made sense.

* Express (GLSL expression, possibly known value) pairs as a classGravatar commit-bot@chromium.org2013-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
