Review request for Calligra and Sven Langkamp.


Description
-------

The outline generator is used in two places: to create brush outlines and to create outlines for selections. It works on a raw byte array. For selections, that array can be very big. This patch adds a version of the outline generator that works on paint devices. For optimization, the random accessor is shared. The paint device version also doesn't use a width * height char array for the marks, but a paint device. This saves memory because paint devices are sparse by nature.


This addresses bug 285775.
