Incorrect min_y?

[bugadani]

Based on this metric I believe the linked line may be incorrect.

If that's supposed to be height, I'm happy to fix it, otherwise please provide an explanation why it's width.

[jamwaffles]

Yeah that definitely looks like it should be height - 1. There's a similar block of code here, so it might be worth moving the min/max reset into a private method.

I haven't given it much thought, but shouldn't these be rotation aware values? Is min_y the same when rotated by 90 or 270 degrees?

[therealprof]

Yes, there're the other variables which take the rotation into account. However it's a bit weird to have the manual comparison in the code. There're max() and min() functions for that.

You mislead me :) That block is marking the whole display to be updated, the original block resets the area to nothing.

Oop yes you're right, min/max are swapped there. My bad!
