Some investigation of #2, inside ImageIOImage#loadBitmap:
alphas = { 0, 255, 255, 255 }
reds = { 0, 0, 187, 1 }
greens = { 0, 0, 224, 2 }
blues = { 0, 0, 227, 3 }
The first palette colour is the transparent colour, which is black. The second
colour, which is *not* transparent, also happens to be black.
FOP assumes that the transparent colour doesn't occur anywhere in the image, yet
in this situation it does.
Maybe it would be possible to pick an RGB combo which doesn't exist in the
image, recolour all the transparent pixels to that colour and then set that as
the transparentColor field. That way it wouldn't clash with real drawn pixels
which happened to have the same colour.

When building the bitmap array, offsets the stored image pixels.
