* 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.

* Introduces new SingleTextureEffect base class for GrCustomStage objects.Gravatar tomhudson@google.com2012-07-12
| | | | | | | | | | | | | | This class tracks the texture that the object uses. A future commit will get rid of the GrTexture pointer currenty stored in the GrDrawState, allowing us to have CustomStages *without* textures.

* fix warnings on Mac in src/gpu and include/gpuGravatar caryclark@google.com2012-06-06
| | | | | | | | | | | | | | | | | | Fix these class of warnings: - unused functions - unused locals - sign mismatch - missing function prototypes - missing newline at end of file - 64 to 32 bit truncation The changes prefer to link in dead code in the debug build with 'if (false)' than to comment it out, but trivial cases are commented out or sometimes deleted if it appears to be a copy/paste error.
