Tiled painting mode in ArmorPaint,

Hi,

Any chance this could be added to Armor Painting brush features:

Tiled Painting mode would very useful if you are painting Atlas and trim sheets.
I am aware of symmetry painting in Armor paint but with tiled painting we can set the tile size in pixels and paint.

Start by reviewing ArmorPaint's brush features and existing symmetry painting, then watch the linked tiled-painting example to define the behavior. Confirm how tile size in pixels should work for atlas and trim-sheet painting; done means a tiled painting mode that repeats strokes using the chosen pixel tile size.
