Pixels, not bytes, unless you were thinking about 8 bpp paletted images.
I don't see -- in the almost nonexistent docs -- that windres actually
supports PNG icons. windres.exe isn't linked to cygpng*.dll on my
system, so if it does support PNG icons, it must do so only by blindly
copying the PNG data into the COFF file.
Is that something we should add, too?
The only time I've found where I can tell that a program has a high-res
icon is by looking at the blue info bar at the bottom of Explorer
windows. A little poking around suggests that at least 64x64 is useful
with the default bar size. You can resize it to make Explorer use a
larger icon, if available, but I doubt many ever do that.
For XP support, we still need to ship 32x32 and 48x48 pixel icons.
