For some reason, GLES has no glMapBuffer, only glMapBufferRange. GLES 2 has no buffer mapping at all, and GL 2.1 does not always have glMapBufferRange. On those PBOs remain unsupported (there's no reason to care about GL 2.1 without the extension). This doesn't actually work on ANGLE, and I have no idea why. (There are artifacts on OSD, as if parts of the OSD data weren't copied.) It works on desktop OpenGL and at least 1 other ES 3 implementation. Don't enable it on ANGLE, I guess.
