Now that collision masks have been added, how about adding masked filters, which you can add to a sprite then specify which area the filter acts in a similar way to collision masks. Would be awesome if you could add multiple filters to different areas of a sprite.
I think this would have loads of applications, in an RTS for changing the colour of particular areas of units
for rpgs changing colour of clothes for different items or whatever (but not changing the colour of the entire animation)
obviously there would be loads more uses
upper body is what this can do, legs are what current filters can do
even with bones its still annoying having to use 2 objects for this.
say you wanted to change a player's eye colour, but didnt want to change the colour of their entire head or use 2 objects.
EDIT: support for transparency would also be really good
