Module Name:    src
Committed By:   rin
Date:           Fri Aug  2 04:39:09 UTC 2019

Modified Files:
        src/sys/dev/rasops: rasops1.c rasops2.c rasops24.c rasops4.c
            rasops_bitops.h

Log Message:
Add general putchar functions for 2 and 4bpp.

Note that 1bpp continues to use its local version in rasops1.c,
which is much faster and simpler.
