							graphicsdriver/opengl: Fix suspicious GL function calls

						Before this change, the pixel object buffer is unbound just after
getting a pointer by glMapBuffer. This seemed suspicious.
This change fixes to do all pixel manipulations once between
glMapBuffer and glUnmapBuffer without changing a bound buffer.
This might fix a wrong rendering on some machines, but I am not
sure.
