Selection: Moore's neighborhood walk replacement for SimplifySelection #526

factored out rasterization so that it's more generic and could possibly be used elsewhere.
moved PointContainer class to UtilityClasses
added "GetPixel" functions to BitmapUtilities to get the value of a pixel in any bitmap (only supports GRAY8 and RGBA32 for now)

it's not perfect but imho it's categorically better than master, unless I haven't found bugs. A few comparisons; sorry, the screenshots don't exactly match but you can see the difference:

master: 001b-sel

this PR: 001sel

master: 003b-sel

this PR (not perfect, but better): 003sel

master: 004b-sel

this PR: 002sel

Nice! Getting these things right isn't something one expects to be such a challenge, but they are fundamental. Good work!
