How to detect display speed in custom widget?

[Daniel Yek <dyek real com>]

Hi,

(I didn't get a response at gtk-app-devel-list gnome org  
Technical-wise, gtk-devel-list is the best list for this question...I'm 
hoping someone would have an answer for me.)

I'm wondering if anybody is experienced in writing smart widget that 
would react differently depending on whether the current display is 
local/fast for graphics animation or remote/slow where all animation 
should be kept to the minimum?

What techniques are suitable for drawing speed detection?

Thanks a bunch.
