Enable multi-sampling on floating-point color renderbuffers |
||||||||||
Issue descriptionAccording to the WebGL EXT_color_buffer_float Extension -- "Multi-sample floating-point color renderbuffers may optionally be supported. Applications must follow the limitations defined in the EXT_color_buffer_float extension, and check for framebuffer completeness after attaching such a renderbuffer.", so we now need to relax it in chromium appropriately.

This CL simply relaxes it.
