[Mesa-dev] [PATCH] mesa/main: correct validation for GL_RGB565

[Erik Faye-Lund]

Technically speaking, this validation was incorrect, because GL_RGB565
is only supported in OpenGL ES 1.x if OES_framebuffer_object is
supported. This couldn't lead to any real incorrect behavior, because
all drivers support OES_framebuffer_object. But let's keep the code
self-documenting, by correcting the check as per the spec.
