Review request for kwin, Martin Gr=C3=A4=C3=9Flin and Fredrik H=C3=B6glund.
Changes
-------
adjust the patch to latest changes upstream
Summary
-------
This patch adds an optional texture cache to the blur effect. The texture c=
ache allows one to partially repaint the blurred region
if the region or a window on top it is damaged. This patch does not change =
anything on the behavior of the blur effect if caching is turned off.
Some facts about the texture cache:
- It does not a full cache of the window's background. To achieve this one =
would have to shrink the clip of all following windows which results in les=
s performance.
- We only cache the horizontally blurred texture. I didnt test whether it i=
s better to cache the full result.
- For every window we have to keep a texture of the size of the blurred are=
a in the GFX memory.
Although we so far only cache all windows or none the prePaintWindow functi=
on is designed to add the possibility to decide on a per-window basis which=
window
should be cached. But IMO this is not worth the effort cause the extra memu=
sage isnt that high.
