Subject: The colormap code is now simpler, 15bpp works where it did not before.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a38aef93ab2a5006c3b8cfa50aaf48fafc0eb8d4;p=mesa.git

The colormap code is now simpler, 15bpp works where it did not before.

The input is fixed so that delete reports '\b' and backspace 127

The vt switching works both right and left.
