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 gdisp_lld_fillarea() is defined there is little
point in defining gdisp_lld_clear() unless the
performance bonus is significant.
For good performance it is suggested to implement
gdisp_lld_fillarea() and gdisp_lld_blitarea().
