Another reason why Quartz is slow may be in the current math library

a 10x factor, though).
The MacOS 9 math lib was much faster than the currently used one, and I
guess Quartz is doing a lot of trigonometric calls (even if common
cases are
optimised manually).
I heard Apple is working on this, however. (well, the bug has been filed
numerous times, and it is in the opensource database...)
I think Apple moved to a PPC assembly mathlib in 10.1...
