[webkit-dev] webkit gtk paint

[zaheer ahmad]

hi all,

The current paint algorithm in webkit (gtk port) requests all the objects in
the clip region to repaint itself to the cairo surface. This seems terribly
slow on a embedded arm platform (400Mhz, 64M Ram, takes >200ms) for a
scroll. we are expecting a >20FPS response speed to enable a smooth scroll
on a touch h/w without graphics gpu support. i remember reading a post where
cairo double buffering was a option to improve the same. Appreciate any
inputs on the same.

thanks,
Zaheer
