And it's been a while since 0.7 anyway.

such that texture objects need to be recreated.

If there's an 8th numeric field in a .wf file, take it to be a focallen distance.

Pass the news to the texture layer so we don't lose textures.
Or at least so we can arrange not to lose em, not sure this works yet...

Add hooks for Toshiyuki Takahei's FLHACK FLTK stubs.

it seems to get the data completely wrong (most X's = 0, etc.).

Move colorpatch::draw()'s body here.
