Here is a patch to remove the unused old code in bitmap.c.
To explain what this old code is, when 15+ bpp color was added to
rdesktop, there was one bitmap decompression algorithms. It checks
the bpp for each pixel decompressed. It was split up into 3 faster
functions about three years ago, there was a define to use the old
code. There was no configure option for it and as far as I know, no
one ever used it. The old code was only slightly smaller and much
slower. This patch removes the old code.
In the past I wouldn't even inform the list of something like this but
we are trying to be open about everything.
