Fix framebuffer attachment validation.

GL_BACK, GL_DEPTH, and GL_STENCIL are only valid for the default
framebuffer, while GL_DEPTH_ATTACHMENT, GL_STENCIL_ATTACHMENT,
GL_DEPTH_STENCIL_ATTACHMENT, and GL_COLOR_ATTACHMENTi are only valid
for non-default framebuffer objects.

Also implement the color encoding query.
