Hi all,

This patch series contains fixes and improvements for the XRGB888 to
monochrome conversion in the DRM core, and for its users.

This has been tested on an Adafruit FeatherWing 128x32 OLED, connected
to an OrangeCrab ECP5 FPGA board running a 64 MHz VexRiscv RISC-V
softcore, using a text console with 7x14 and 8x8 fonts.

Thanks for your comments!
