Florin Malita fb4bce8322 [sksg] Refactor gradient implementation ... Currently, gradients are PaintNode subclasses - which limits their applicability to leaf DAG nodes. In order to support generalized gradient/shader effects: * introduce a new Shader base class * refactor gradients as Shader subclasses * introduce ShaderPaint (to support current Gradient-as-paint use) * introduce ShaderEffect (to support future Gradient-as-effect use) Tangentially: * rename SkSGPaintNode.h -> SkSGPaint.h * consolidate sksg::Color into SkSGPaint.h Change-Id: I94ba949f4504c09cfde4a4f030d927411fdd66a2 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/205263 Reviewed-by: Mike Reed <reed@google.com> Commit-Queue: Florin Malita <fmalita@chromium.org>		2019-04-01 18:43:43 +00:00
