Hi. How about turning off HTML mail before posting to a mailing list?
Or, better, just turning it off for good? ;-)

An alternative approach is to use a separate 1-pixel-high
gl_putboxmask() for each pixel line. This avoids having to copy twice,
which may make it faster despite the multiple calls.
Here's roughly what I mean (untested):
for(i=0;i<src_h;i++)
gl_putboxmask(dest_x,dest_y+i,src_w,1,
src_pixmap+((src_y+i)*src_pixmap_real_width+src_x)*bytes_per_pixel);
Obviously you could optimise this somewhat by keeping a current
pointer for the last arg rather than recalculating it each time.
