Just wanted to point out that since there is no floatless option for
Cairo, you will definitely want to be using an EABI system on
non-FPU devices. The performance impact is huge.
And as Daniel said, profiling and/or providing problematic test data
always helps push things forward. The Cairo developers are always keen
on solving the issues :)
