If you specify zero for depth_bits, stencil_bits, accum_[red|gren|blue]_bits, you can save some memory.
UGL_MESA_DOUBLE = double buffer mode, first tries hardware mode and then software mode
UGL_MESA_DOUBLE_SOFTWARE = double buffer software, fails if impossible
UGL_MESA_DOUBLE_HARDWARE = double buffer hardware, fails if impossible
UGL_MESA_WINDML_EXCLUSIVE = uses only WindML calls to write into the memory screen
For example, uglMesaCreateNewContext(UGL_MESA_SINGLE | UGL_MESA_WINDML_EXCLUSIVE) will use a single buffer and will only write into the screen memory with WindML calls. UGL_MESA_DOUBLE_SOFTWARE will be replaced by UGL_MESA_DOUBLE in WindML mode. There is no sense to use single and double buffer at the same time.
depth_bits - depth buffer size
stencil_bits - stencil buffer size
accum_red_bits - accumulation red buffer size
accum_green_bits - accumulation green buffer size
accum_blue_bits - accumulation blue buffer size
accum_alpha_bits - accumulation alpha buffer size
share_list - specifies another UGL_MESA_CONTEXT with which to share display lists. NULL indicates no sharing.
