As you might know I am using cairo in OpenOffice canvas implementation
for some time. It works pretty well, but it is still reaching some
bottlenecks. I think the most critical part for us are slow compositions
of large surfaces with alpha channel.
might be used as test case, it contains 162 types of slide transitions.
Open it in OpenOffice, make sure you have the cairo backend enabled
(menu Tools/Options... in dialog enable OpenOffice.org/View/Use hardware
acceleration). Press F5 to run slideshow. Most of them run reasonably
fast, but some are slower - these with non-rectangular drawing - like
#48 ellipseWipe or fading ones #153 - #156.
I heard there is a small library, which can be preloaded which helps to
trace cairo calls/usage. Could you point me to it, so I can try to get
you simpler test case(s)?
