The selection-border corners were designed to be an overlay over the
edges, but GUI2 uses them adjoining to the edge images.
This has been fixed by manually overlaying them in the images
themselves.
This directory contains the images used to assemble dialogues. Each group of
images is named by the part before the first dash, which is a style
referenced by name in the Wesnoth UI code.
The 'transparent' images have some alpha transparency; they look like
smoked-glass overlays on the terrain or whatever else is underneath
them. Each transparent style has a suffix which is its opacity
percentage (100-alpha). The 'opaque' images are geometrically the
same, but opaque. They could be called 'translucent100', but aren't
for reasons that are basically historical.
Note that the translucent and opaque styles differ only in the background
images, sharing borders. This uses a little more space but simplifies
the code.
The directory also contains some background images of different opacity
levels, just so they're handy for tuning. They cost less than 0.5K each
to keep around.
