2013-11-01Make GrContext cache the gpu pathscommit-bot@chromium.org
Creating paths for nv_path_rendering is costly. Try to reduce this cost by caching paths based on the SkPath "hash" (i.e. SkPathRef generation id) and stroke properties. Adds the paths to GrContext::fTextureCache instance. Later this should be renamed and the GrContext API should reflect the nature of the cache better.

2013-10-09Implement stroking a path with nv_path_renderingcommit-bot@chromium.org
Initialize the path stroke properties in the GrGLPath constructor. Use StencilStrokePath and CoverStrokePath to stroke the path. The order of the GL calls is: 1. StencilFill, if needed 2. StencilStroke, if needed 2a. CoverStroke, if stroke was applied 2b. CoverFill, if stroke was not applied The reason for not pairing StencilFill + CoverFill, StencilStroke + CoverStroke is that Skia API does not allow separate fill and stroke color within one call. Covering the stroke bounding box should also cover the fill bounding box. Causes different rendering in gm/dashcubics due to different rendering algorithm. (?) (TODO: this should be resolved somehow.)

2013-10-09Implement filling a path with nv_path_rendering covercommit-bot@chromium.org
Implement filling a path with nv_path_rendering cover functionality. The nv_path_rendering cover can be used if the fill is non-inverted and the draw operation does not require use of vertex shaders. Moves code for the inverted fill from GrStencilAndCoverPathRenderer down to GrGpuGL.

2012-12-17Follow up on the previous patch :sugoi@google.com
- Moved the SkStrokeRec class in its own file - Replaced SkStroke by SkStrokeRec in Ganesh - Moved path stroking to the Ganesh level in some cases (everytime it isn't required to do it directly in SkGpuDevice). PathEffect and MaskFilter still require path stroking at the SkGpuDevice for now. - Renamed static functions in SkPath with proper names * No functionality shold have changed with this patch. This is a step towards enabling Ganesh Path Renderers to decide whether or not to stroke the path rather than always receiving the stroked path as an input argument.
