Hello Shelley Chen, build bot (Jenkins), Joel Kitching, Julius Werner,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

Change subject: libpayload: cbgfx: Add color mapping functionality

libpayload: cbgfx: Add color mapping functionality

Similar to set_blend(), add set_color_map() for mapping background and
foreground colors of a bitmap. Also add clear_color_map() for clearing
the saved color mappings.

Note that when drawing a bitmap, the color mapping will be applied
before blending.
