[Freeciv-Dev] (PR#12590) some logging code for drawing pixbufs/pixmaps

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=12590 >

This patch logs the number of sprites drawn, and what percentage of them 
have alpha levels (e.g., use pixbufs).

For isotrident it takes about 2000+ sprites to draw the mapview in 
default resultion.  It takes 5000+ sprites to draw it in fullscreen 
(1280x1024).  Of couse even in fullscreen the panel and chat tab take up 
a large portion of the screen.  About 8% of the sprites have alpha. 
These are all with a late-game savegame.  Lots of terrain improvements 
means lots more sprites; this is the worst-case which is what we should 
be worrying about.  But note that these "extra" sprites all don't have 
alpha; in an earlier game you'll get fewer sprites but a larger % of 
them will have alpha.
