[cairo] cairo run on mips without FPU

[maddrone]

hi guys:
   i am porting the Swfdec+Cairo to a handle device with a 330M mips CPU,without FPU and GPU, all work down by the CPU, to play the Adobe Flash.

  And i found the performance is very very low in Cairo Render stuff. So i optimize the Lib Cairo , to transfer some "Float Multiply" to "fixed Multiply", the speed is faster,but still
not acceptable.
  The Question is: Colud anyone help me 
to figure out the "KEY POSITION" i should optimize.
