[Gnash-dev] Update region detection?

[Udo Giacomozzi]

Hi,

does Gnash contain / is it planned that Gnash will detect the screen
region (upper-left and lower-right coordinates) where characters did
change visible?

Currently Gnash seems to redraw each frame from ground up even if just
a small portion of the screen did change and even if there was no
change at all (ex. stopped movie).

This would *really* speed up rendering.

Just want to know if Gnash contains some attempts of if I may
integrate it from ground up...
