I think it should be higher.  I get "Time = 0.931021 s, FPS = 322.227"
on a Core2Duo 1.83 GHz, in release mode.  I am running in 32-bit mode.
I assume you are in 64-bit mode, and the float->int trick might not have
been enabled.  Can you check that by forcing the inline function in
aintern_float.h?

My results for ex_prim are much worse; ~3.7 FPS in software mode with
blending.

Is that this line in your revision?

   ASSERT(height >= 0);

I guess depending on the rotation of the shape and the thickness, etc.
it's trying to draw outside the bounds.  Paul, can you take a look?
