I don't know how much I really like those for the outdoor cobblestones - each 
tile just seems a bit big for the outdoor scale.  OTOH, I think those would 
probably look fine for indoor graphics for tiled floors and whatnot - while all 
images are the same size, the perceived image of indoor stuff being smaller 
scale than outdoor.

  I guessed I never noticed that much.

  If you use SDL graphics, true alpha support should be present.

  If using gtk graphics, then true alpha support is not present - you can have 
transparent and opaque, and nothing in between.

  I don't expect this to change - the gtk code uses the drawing primitive that 
gtk provides, and these don't allow for true alpha (this is probably because for 
xwindows, those calls pretty directly translate to the x11 image drawing 
functions, which don't support true alpha).

  So that said, I don't see there being much of a problem with making images 
with true alpha qualities, but it shouldn't be presumed that the client will 
display them properly.  Meaning basically, you could put in drop shadows or 
other such bits, and verify that the image looks OK with non true alpha.
