Request: Alternate Clear Canvas modes

[wbochar]

Using alternate Keys,

Shift-Click Clear Canvas: Should remove any select character in the font palette Shift-Control-Click Clear Canvas: SHould remove any characters/colours not visible to the BG Colour and a Blank character. There always seems to be stuff hiding in the edges...

Nice feature, especially the latter one.. Been wanting to throw out all sorts of invisible thrash myself too.

I got a really big surprise in my last project, where I did $d800 fades by going to white down to dark gray for the whole screen. A bunch of old text started flashing out that was hiding in the black areas. Because the piece was very busy, it was a real pain to fix.
