[Tilecache] Text labels getting smudged with tilecache

[louvy.joseph at gmail.com]

Fonts are getting smudged/smeared through tilecache while the same tile 
if not passed through tilecache comes out much crisper from the 
geoesrver. Has anybody seen this issue? It does not happen for every 
text label though. Lines or points are fine; the problem is only with 
the labels. I am guessing that this is some kind of problem with PIL. 
Isn't the PIL supposed to blindly cut the metaTile? Why would it change 
the colors? Has anybody seen this? And what could be the root cause?

Thanks in advance..
