PNGLoader: Reduce unfiltering branchiness even more.
Use a dummy scanline for y=0 filled with all zeroes to avoid having to check
y on every iteration before grabbing color data from scanline[y - 1].

PNGLoader: Templatize the unfiltering functions to reduce branchiness.
This also allows us to dodge processing alpha values in non-alpha PNGs
without a branch.

PNGLoader: Allocate enough space for the compressed data buffer up front.
This is a 2x speedup on wallpaper loading.

PNGLoader: Remove a bunch of unnecessary data copying.
Use ByteBuffer::wrap() to avoid copying buffers around a bit. This is about
a 10% speedup on loading a wallpaper-type PNG.

SharedGraphics: Implement a simple PNG decoder.
This is extremely unoptimized, but it does successfully load "folder32.png"
so it must be at least somewhat correct. :^)
