Floating point in pango

[Jorn Baayen <jorn openedhand com>]

Hi,

Just FYI, GTK+ >= 2.8 uses pango-cairo to draw text, which apart from
using cairo to draw also calculates the position of each glyph using
floating point whereas this was done using fixed point previously. 
Pango-cairo alone appears to be responsible for an approximately 30%
slowdown when drawing text on ARM.

Thanks,

Jorn
