*
* The controller has some quirkyness when operating in other than rotation 0 mode.
* When any direction is decremented it starts at location 0 rather than the end of
* the area.
* the area. Whilst this can be handled when we know the specific operation (pixel, fill, blit)
* it cannot be handled in a generic stream operation. So, when orientation support is turned
* on (and needed) we use complex operation specific routines instead of simple streaming
* routines. This has a (small) performance penalty and a significant code size penalty so
* don't turn on orientation support unless you really need it.
*
* Some of the more modern controllers have a broken command set. If you have one of these
* you will recognise it by the colors being off on anything drawn after an odd (as opposed to
* even) pixel count area being drawn. If so then set GDISP_GE8_BROKEN_CONTROLLER to TRUE
* on your gdisp_lld_board.h file.
* on your gdisp_lld_board.h file. The price is that streaming calls that are completed
* without exactly the window size write operations and where the number of write operations
* is odd (rather than even), it will draw an extra pixel. If this is important to you, turn on
* orientation support and the streaming operations will be emulated (as described above).
