Limitations
-----------
I found the following limitations in my driver :
- Color Indexed management is only in 8 bits
- The front and the back buffer must have the structure (mode and
size). A structure umc->buffer is requisite if the front and back
buffers are different.
- It isn't possible to mix UGL/OpenGL application with a software
double buffer (to fix)
- It's possible to mix UGL/OpenGL application with a software
double buffer
