Can the mesh elements overlap within the input coordinate space?
For example, just say I have a window that's 800x600 at (0,0) and I want to
display and interact with a zoomed fragment from the middle of it (think
interactive screen magnifier, or something similar)
This means I'd want to have the input at (for example) a 400x400 area at
(1000,0) as well as the regular window location.
(side note - Sorry if I'm being incoherent, today is just a very braindead day
for me =/)
What good is a ticket to the good life, if you can't find the entrance?
