What & why

Attempts to rework object placements to snap them to device pixel space to improve sharpness at fractional scaling.

New component

SnapLayout now acting as an almost-drop-in replacement for Qt's ColumnLayout and RowLayout It positions children properly in device pixel space.

New helpers

ZUtils has three new helpers:

• snap(v, item)
• snapCeil(v, item)
• snapFloor(v, item)

Snaps v to item's device pixel space.
