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. Updates #993
