Hi,

Sometimes, drawterm begins to print blanks instead of
glyphs. This happens with X11 drawterm with some hardware
and drivers. 

It happens because Xfree86 drivers for some video cards assume that
masks (stipples) must have height equal to a multiple of 8. This
causes drawterm to display blanks instead of glyphs with some fonts.
To use drawterm with these drivers, the patch at 

http://ftp.davidashen.net/misc/drawterm-stipple.diff

can be applied to the source (/sys/src/cmd/unix/drawterm).
drawterm will become slightly slower, but will not loose glyphs
any more.

Use ape/patch to apply the diff.
