[libcaca] Re: updated patches for libcaca
updated it again, new URL:
http://zoehep.xent.com/~bsittler/libcaca-trunk-1125.diff
changes:
* caca/driver_x11: fixed data for left and right tee
* cucul/transform.c: add flip, flop, and rotate data for addition
cp437 box drawings
* cucul/charset.c: improve ASCII mapping for upper half block and
lower half block so they are distinct, this allows using them for
pseudo-bitmap graphics with each character cell holding two bits
there is a corresponding version of myman (same URL as before):
http://zoehep.xent.com/~bsittler/myman-0.7pre1.tar.gz
now it can approximate the look of the arcade game with reasonable performance:
env CACA_DRIVER=x11 CACA_FONT=nil2 ./myman -z bitmap2
there is a known rendering bug: myman does not support background
colors other than black yet, so when two colors combine in a single
character cell only one is visible. i hope to fix this eventually. to
see a non-buggy version which is also twice as big:
env CACA_DRIVER=x11 CACA_FONT=nil2 ./myman -2 -z bitmap
do let me know if you have any questions or comments.
thanks,

I was thinking about that. Either a string, or a uint16_t that has
an optional MSB with a character value, which is easier to handle (no
allocations) but slightly ugly.
or a separate call to get the right hand side?
