really? very interesting as i'm getting my own mmx asm bleding routines blending
@ 32bpp being 35 times faster than xrender (blending at 1:! scaling, no
transform, nearest filter for scaling).
display is 24bpp (src picture is 32bpp, with alpha, component alpha set, repeat
set to true, dither true). i am not sure.. but a 35 TIMES speed difference with
software being the faster... sounds wrong to me.
