Hi,
I came across some troubles with colorkeying on savage driver.
>From the sources I saw that there is a different handling with color key set
to zero vs. non-zero. From my opinion black should be treated as other colors
too.
I'd like to get some comments from driver developers.
@ Angelus: Havn't seen your bugreport so I'll posted this on X-devel.
