Subject: [PATCH 1/2] Correct GL_BACK/GL_BACK_LEFT mapping on GLES
GLES does not have LEFT/RIGHT targets for the default framebuffer, but
just GL_BACK, so there is no need to remap it. Desktop GL may have
LEFT and RIGHT attached at the simultaneously, so one of the buffers
has to be selected when querying the attributes.
