i r stupid
The sample replacement loop I sent before was incorrect after all. I was
the pointer srcp (which is of type CARD32*) by an amount of src_pitch
in bytes). Duh. No wonder pixmaps appeared squished.
Attached is a fixed patch which properly removes the EXA breakage.
However, I am
still looking for a reference of commands available through BCI. Window
is awfully slow, even with EXA fixed, and I wonder what EXA operations
accelerated in order to fix this. An interesting observation: under EXA,
for simple composition actually makes window dragging *faster* than
* EXA upload to screen must honor pitch of the source data
