Is this really so helpful?
If you want to enter some exact size to the render border I would
imagine you would want to adjust the render border directly.
There are 3 obvious cases you might want more precise control...
- Getting exact pixel dimensions
(eg: render a 512x512px rectangle from a larger image)
- Rendering an exact division of the view
(eg: bottom half, left side, exactly half the original size by
adding a margin)
- If you want to constrain to a fixed aspect ratio.
Being able to enter in mouse coords exactly doesnt help much with
either of these since screen coords don't map to camera view coords.
Having better ways to manipulate render border is reasonable, but I
think showing mouse coords isn't really giving the user a useful way
to do that.

I think we could better have some custom widgets for this,
If a tool needs a line or rectangle, we could have a way to create
that and interactively edit it (constraint aspect, snap, numeric

Really rather not, the buttons and their values are near meaningless
from the users point-of-view.
