[PD] low color.depth in gemwin

[Peter Todd]

I have found, on my system (radeon 9000 mobility, windowsXP, latest stable 
GEM 0.90 binary release etc etc), that although the colour depth is sensible 
most of the time, basically any time I use [pix_texture], it is not.  If 
someone could shed any more light on this, or suggest a solution, it would 
be much appreciated.

  GEM will use a 24 bit buffer for its OpenGL output regardless of the 
current
  windows display depth.  If the display colour depth is lower than this, 
then
  dithering will occur (down to 16 or 8 bit or ...) before it appears on 
your
  monitor.

  So, ensure your windows display depth is set to a reasonable value (prob 
16,
  24 or 32 bit).

  The OpenGL rendering occurring on any particular machine will be either an
  accelerated driver associated with your video card, or the microsoft
  software renderer.  The appearance and performance of the various 
renderers
  can vary considerably.
