2012-09-11Avoiding X server leaks with XftColor cacheJose Antonio Ortega Ruiz
This patch is a first complete solution to the long-standing memory leak (on the X server side) caused by repeteadly asking the server to allocate XftColor instances. Despite the fact that we were freeing them, the server didn't seem to care... this was also happening for non-Xft Colors, and solved in the same way we'd done here, i.e., by caching XftColor instances. And additional complication has been that Graphics.X11.Xft doesn't export any function to create and retain an XftColor, nor the necessary datatype constructors to write a compatible version outside the module (there's no way to construct an XftColor instance to pass to the other functions in the library). So, i've created my own lite version of the whole module, until the day it supports XftColor creation.
