You're right about mouse-drag-and-drop-region, it doesn't work
correctly when using rectangular regions. After taking a look at the
code, I managed to fix two things: the dragged text now has the
correct rectangular contents (but the original text is incorrectly
deleted using a normal region), and the tooltip displaying the dragged
text also shows the correct contents.
To fix the rest of the functionalities, I would need to know the
recommended way of handling some of the details of how
mouse-drag-and-drop-region is implemented:
- The dragged region is tracked using an overlay. From what I
understand, this is a problem since overlays only handle regions
with a single beginning and end, and rectangles have one or more of
those.
- In order to check if the dragged text is read-only, the function
"next-single-char-property-change" is used. This function has the
same problem as the overlay, as it assumes the region is contiguous.
I'm thinking both problems could be solved by using a list of overlays
instead of just one, creating them from the result of calling
"region-bounds". Then, the rest of the function could be adapted to
use the overlay list.
