All the below routines are optional.
Defining them will increase speed but everything
will work if they are not defined.
If you are not using a routine - turn it off using
the appropriate GDISP_HARDWARE_XXXX macro.
Don't bother coding for obvious similar routines if
there is no performance penalty as the emulation software
makes a good job of using similar routines.
eg. If gfillarea() is defined there is little
point in defining clear() unless the
performance bonus is significant.
For good performance it is suggested to implement
fillarea() and blitarea().
