Original issue's description:
> Implement support for CHROMIUM_path_rendering pseudo extension
> 
> Implement support for path rendering in Chromium through
> CHROMIUM_path_rendering pseudo extension.
> 
> The extension defines a new pseudo-gl function,
> BindFragmentInputLocation. This behaves similarly to the
> BindUniformLocation pseudo-gl function. The idea is to assign fragment
> input location to a fragment input before linking the program.
