<pre>I try enable fastfb on rs740 and have much better result: 45ms in my test and
45.7ms in Chris test.
Without fastfb I have 135ms in my test and 800-650ms in Chris test.
Also I have big difference in gtkperf ("gtkperf -ac 1000" on full screen).
With fastfb:
GtkEntry - time: 0.11
GtkComboBox - time: 3.08
GtkComboBoxEntry - time: 2.42
GtkSpinButton - time: 0.22
GtkProgressBar - time: 0.17
GtkToggleButton - time: 0.24
GtkCheckButton - time: 0.22
GtkRadioButton - time: 0.82
GtkTextView - Add text - time: 16.23
GtkTextView - Scroll - time: 0.11
GtkDrawingArea - Lines - time: 8.11
GtkDrawingArea - Circles - time: 10.11
GtkDrawingArea - Text - time: 15.80
GtkDrawingArea - Pixbufs - time: 1.72
---
Total time: 59.36
Without fastfb;
GtkEntry - time: 0.13
GtkComboBox - time: 4.25
GtkComboBoxEntry - time: 2.63
GtkSpinButton - time: 0.26
GtkProgressBar - time: 0.43
GtkToggleButton - time: 0.52
