Repaint region callbacks

[ariya]

downch...@gmail.com commented:

WebKit inspector has an option to report on regions that are repainted (height and width); it'd be nice to have something like that in the phantomjs API to make it easier to detect when only a portion of the screen has changed. The repaint API may require a raster call, or it may simply work as a general callback; in either case, it seems that WebKit does support reporting on the geometry of repaints.

Due to our very limited maintenance capacity (see #14541 for more details), we need to prioritize our development focus on other tasks. Therefore, this issue will be automatically closed. In the future, if we see the need to attend to this issue again, then it will be reopened. Thank you for your contribution!
