Add GL_CHROMIUM_screen_space_antialiasing to support alternative AA
MSAA is very expensive on some platforms. We introduce extention
GL_CHROMIUM_screen_space_antialiasing to support other antialiasing
approach. It will perform antialiasing to the color attachments of
the currently bound draw framebuffer. As an example, we implement it
using GL_INTEL_framebuffer_CMAA which results in similar quality of
MSAA at better performance.
