cai's split gradient patch

[David Barr]

Hello,

Cai, from #openbox (on oftc.net, if you want to 'hang' - as the kids
say) made this (awesome) patch that makes a split gradient option,

https://bugzilla.icculus.org/show_bug.cgi?id=2509

you just use "split" as a normal gradient option instead of vertical or
whatever.

i made a screenshot the probably explains things better than i ever
could:

i think it is pretty super and i think it might be nice for more people
to try it.

that is all - 5 cheers for cai!

David
