winex11: Keep some last unused font cache entries in cache a bit longer.

[Ričardas Barkauskas]

This helps scrolling on Steam store page by lowering percentage spent in 
SelectObject from ~6% to ~0.8%. This slow down becomes especially 
noticeable on some special promotions shown on the page. This happens as 
application goes selecting some fonts in a loop which are not yet in 
cache forcing them to overwrite each other in the cache. Causing font 
cache entries stay until font is somehow deleted maybe would work for 
gdi32, but would fail for gdiplus anyway, as it creates/deletes fonts 
with gdi functions on every text output.
If there's better way to do this, please suggest.
