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.
