skia2/gpu/include/GrTesselatedPathRenderer.h
senorblanco@chromium.org 9d18b7873c This CL implements a tesselated path renderer, using GLU's libtess. All of the
fill modes except hairline are supported.  Note that the path renderer is not
enabled by default; to enable it, replace "GrCreatePathRenderer_none.cpp" with
"GrCreatePathRenderer_tesselated.cpp" in skia.gyp, and run gyp_skia, and build.

This change also contains a number of build fixes for Win32 (for building
SampleApp on VS2008) and Mac (for my ancient Mac Pro which supports
GL_EXT_framebuffer_object but not GL_ARB_framebuffer_object).  Also,
priorityq-heap.c was removed from the SampleApp build, since it's #included by
priorityq.c (weird, I know).

NB:  When this change is rolled into chrome, some modifications to chromium's
skia.gyp will be necessary.
