-// fix bmp padding for Bitmap function
-// speed up pixel
-// 30.12.11 fix cls
-// 11.03.12 use DMA to speed up
-// 15.03.12 use SSEL for TFT CS to enable DMA Register writes
-// 06.04.12 fix SSEL CS problem
-// 06.04.12 use direct access to the spi register to speed up the library.
-// 11.09.12 switch back to using io pin as cs to avoid problems with SSEL CS.
-// 21.09.12 fix Bug in BMP_16
-// 11.10.12 patch from Hans Bergles to get SPI1 working again
-// 03.02.13 add a switch to switch off DMA use for LPC11U24
