Status
------

This change has been marked as submitted.


Review request for Plasma.


Repository: plasma-framework


Description
-------

Create a cache that has pointers to all the textures that we've generated, so in case we have one already created, we can re-use it.

Testing
-------

see the qDebug (to be removed before commit). 

plasmashell 2> out
$ grep s_cache out | grep ": miss" | wc -l
342
$ grep s_cache out | grep ": hit" | wc -l
126

So still having 3 times more hits than miss, so there's big room for improvement. Good news is that with this, we get a ~25% of memory and bandwidth save, in a per-item basis.


Thanks,

Aleix Pol Gonzalez
