Milestone GRE2GL.DLL

This is the replacement for the standard OS/2 2d driver. Normally, it is implemented in as a direct driver, as a driver that uses the GRADD wrapper, or a driver that uses another wrapper (such as SNAP). This driver takes the PM Graphics Engine requests & converts them into OpenGL requests. It's OpenGL requests are fed into GL2PIPE.DLL, however, it's buffer requirements are handled by the compositor (BUFFCOMB.DLL). Whereas, in the past, the 2d driver had to be implemented for each distinct piece of video hardware, GRE2GL.DLL only has to be implemented once. After it's implemented & installed, there will never be another reason to replace this driver for hardware reasons. This driver should only be replaced for software updating purposes.
