Description pentalis 2010-09-23 15:11:54 UTC

Version:           svn trunk (using KDE 4.4.5) 
OS:                Linux

In the autobrush dialogue, when using square masks, and an angle different from zero or 90, 180 or 270, the corners of the mask extend "to infinity" but they are cut without respecting the angle, so the brush dab as a whole never looks tilted as it should.
An image speaks more than a whole wall of text, so I included a self-explaining attachment. (Fade level increases to the right)

Note that I reported this problem before but with a different bug name so this time I tried to make more clear what the problem is.

Reproducible: Didn't try

Steps to Reproduce:
--Open the config popup of the pixel brush paintop.
--Open the autobrush dialogue.
--Select square mask.
--Change the angle.

Actual Results:  
The brush mask is always an untilted square shape instead of a tilted one (aka: rhomboid shape).

Expected Results:  
The brush mask is a tilted square (rhomboid shape).
