Subject: [PATCH] Add missing guard required for GLES to disable stereo
|
||
|
|
rendering
|
||
|
|
|
||
|
|
fmt.stereo() will evaluate to false for GLES, guard the whole block
|
||
|
|
so GL_BACK_* is not used.
|
||
|
|
Qt already includes the OpenGL/GLES headers, so GL_ES_VERSION_2_0 will
|
||
|
|
be defined for Qt GLES builds.
