Comment:
The issue is not only the extent, but also the resolution.
Yes. This was Martin's point. We've made it so that the display
resolution stays constant regardless of the computational region.
This makes the display render MUCH MUCH faster. The only drawback of
having the display region stay constant in this way is that
d.rast.num won't work as it now is. This is probably fixable either
by modifying d.rast.num or by tweaking the GUI. But it hasn't been as
high a priority as other items yet.
I think it would be useful to have the same system as in gis.m,
i.e. with
one display mode aligning to window size and another mode showing the
exact computation region, i.e. respecting extent and resolution.
I think that these two different modes are fairly confusing to most
users.
Martin has implemented something that I think is much more useful and
easier to understand, and that serves the same purpose. As mentioned
above, the display always fills the window and has a constant
resolution. However, the computational region is shown by a red box
outline. This means you can always tell the region in which map
modification operations will take place, without having a very
strange-looking map in the display window, with a lot of white space
around it.
BTW, would also be nice to add "Zoom to default region" to the menu.
Good idea.
Michael
