* New subclasses for both Gr and GrGL gradient effect classes. Gravatar rileya@google.com2012-07-19
| | | | | | | | | This replaces GrSingleTextureEffect as the base for gradient effects (so we'll be able to do gradient effects without textures), and adds a base class to the GL gradient custom stage implementations (which will soon handle generating the appropriate code to pass colors in and lerp instead of using a cached texture for simpler gradient cases). Also added a custom stage for linear gradients. Review URL: https://codereview.appspot.com/6426049 git-svn-id: http://skia.googlecode.com/svn/trunk@4674 2bbb7eff-a529-9590-31e7-b0007b416f81

* There were three different problems with lighting filters:Gravatar senorblanco@chromium.org2012-07-13
| | | | | | | | | | | | | | | | | | | | | | | 1) Texture offsets (fImageIncrement) have to be signed depending on whether the texture is "right way up" (texture upload) or "upside down" (render target), so the surface normals were coming out upside down. 2) Light normals have to y-negated on upload These two bugs were cancelling each other out in SampleApp, (where we were testing w/textures) but not in Chrome (where we were testing w/render targets). 3) The extract-the-height-from-the-view-matrix hack I was using to compare light positions vs. gl_FragCoord doesn't work in Chrome where we compile with GR_STATIC_RECT_VB, and the view matrix contains more than the viewport transform (to accomodate the canonical vertex buffer). Fixed by passing the destination render target to GrGLProgramStage::setData(), so it can flip the light positions in Y on the CPU.

* This patch implements the diffuse and specular lighting filters in Ganesh. Gravatar senorblanco@chromium.org2012-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | There are three light types for each: distant, point and spot, whose code generation lives in a GrGLLight class hierarchy. This similar to the CPU implementation, where each light type provides a function to compute the vector from the surface plane to the light (surfaceToLight) and to compute the light colour (emitLightColour). Instead of templated member functions, as in the CPU implementation, these are virtual functions to emit the light-specific GLSL code. All of the code for the GPU path lives in the same file as that for the CPU path, SkLightingImageFilter.cpp. In order to provide Ganesh a hook to access it, SkImageFilter now has a asNewCustomStage() virtual, which allows an image filter to return a GrCustomStage representing that filter. Note that this patch does not handle the border conditions correctly (the [top|bottom][Left|Right]Normal() functions in the CPU implementation). That will come in a future patch.

* Minor cleanup in lighting image filters: Made the light color a member of theGravatar senorblanco@chromium.org2012-07-09
