PixelPaint+LibGfx: Allow resizing images and layers

Browse source 
This PR adds resize ability to PixelPaint as per issue 11862.
The previous behaviour was to always rescale the canvas when
resizing an image. This adds a checkbox to toggle between
rescaling, and resizing which blits the existing canvas to
the top left of the new, resized canvas.

As part of this, a new ScalingMode is added to
LibGfx - None.
