background:having android apps run on X11 on base
mesa OES lib: libgles1-mesa-dev libgles2-mesa-dev libosmesa6-dev
what to do:
render all surfaces to program memory.
problems:
1) glMapBuffer returns NULL.OES_mapbuffer seemed not work.
though the extension was available.
2) GL_READ_ONLY , GL_PIXEL_PACK_BUFFER were defined in GL/glext.h or GL/glew.h,
they were not found in GLES2/gl2.h gl2ext/h
did that mean it was not suported in libgles2-mesa?
3)if the code was to be ported to Windows, would OSMesa available in windows?
Please advice how to get the pixels of any surface in RGBA format
thanks
