extend pixeltoaster api to support multiple display implementations per platform

[GoogleCodeExporter]

for example, on windows you may have the choice between DirectX and OpenGL
display - on unix you may have a choice between xlib and ggi/svgalib,
directfb or whatever.

a static system interface should be able to enumerate the displays
available on the platform and let you select the current display
implementation to use at runtime, each display you create afterwards will
use the selected display

you should also be able to use defines at compile time to enable/disable
displays on a platform - for example, you may only want to compile in
DirectX and not OpenGL

i'm dropping this, this is not a high priority - i'm happy with one display 
per-platform at the moment
