Driver VESA_24

This driver is initialized with function:

PegScreen * CreatePegScreen_VESA_24(int Width = 800, int Height = 600);

VESA_24 supports any VESA 24-bit color mode if the complete video memory is accessible in a linear address range. VESA BIOS version 2.0 or higher is required. This driver does not set the video mode at run time; rather, it expects that the desired mode has been set by RTTarget-32's boot code using the GMode command.

Parameters Width and Height are only evaluated by the Windows emulation drivers. On the target, the screen resolution is determined by the current graphics mode set by the boot code through a GMode command.

If the current video mode is not a VESA 24-bit color mode, or the video mode does not use a linear frame buffer, NULL is returned.

This driver is somewhat slower than VESA_8, VESA_16, and VESA_32 due to poor pixel alignment in the video memory.
