tdf#99258 bail out if we fail to reserve the texture + more
(cherry picked from commit d22ca8d8cb050b9006720f39c612c5c32eab8795)
also includes coverity fixes from commits:
coverity#1358428 fix "Null pointer dereferences"
4e07c7e279b21c4ae93b832a65e221e2dab5391d
cid#1358836 reorganize to silence Resource leak in object
6e970c11645f1a05638e49da9e2911fe59628838
Check if we have an OpenGL context before using API that requires it
