[Alephmodular-devel] Clipping oneself into a corner

[Br'fin <br...@ma...>]

Most of the clipping stuff is wonderful and perfect. But I found one 
construct that was lacking. Clipping when you know you're dealing with 
a small part of a whole. Most specifically, this means setting the 
clipping area and redrawing the interface to 'highlight' buttons on the 
main menu. D'oh.

I think I'm going to need to add a scoped view clipping to the buffer 
hierarchy. Unlike clipping objects, it doesn't limit you to a part that 
otherwise ignores the whole. Instead, it sets constraints on the buffer 
as a whole.

Incidentally, if you have a view clipping and a clipping buffer, 
drawing commands (but not necessarily pixel editing) are only going to 
occur in the intersection of the two clippings.

So there will be CClippedBuffer::Ptr get_clipped_buffer(rect) and 
CBuffer::ViewClipLock get_clipped_view_lock(rect) methinks.
