Multiple controller support can now auto-detect hardware capabilities at run-time.

Browse Source 
Specific hardware support can still be turned off or on via macros in gfxconf.h to improve efficiency.
Multiple Display demo updated to match.

/* Uncomment the following lines if you want to use multiple displays on

*
* Change the definitions to suit your hardware.
* Currently all controllers must use the same pixel format.
*
* Remember that GDISP_TOTAL_DISPLAYS above must match the **Total**
* number of displays in your system across all controllers.
*
* Optionally, you can also specify hardware characteristics that are common to
* all your controllers. This significantly improves code and speed efficiency
* as the program doesn't have to detect the hardware method to use on each call.
*
* Hardware definitions can be set to:
* - TRUE - all controllers support this routine
* - FALSE - no controllers support this routine
* - if not specified then the code auto-detects the hardware.
*
* e.g
* #define GDISP_HARDWARE_STREAM_WRITE FALSE
* #define GDISP_HARDWARE_STREAM_READ FALSE
* #define GDISP_HARDWARE_DRAWPIXEL TRUE
* #define GDISP_HARDWARE_FILLS TRUE
