Shapes and Rasterization
When a group becomes rasterized, all masks, shapes, and paint strokes in that group are
affected and may no longer interact with other layers and groups as expected.
Because paint strokes are rendered in a plane, they are always rasterized (independent
of other objects in the same group). This affects how the dabs that comprise a paint
stroke interact with objects in the same group.
Note: Because a paint stroke is always rasterized, no rasterization indicator appears around
the paint stroke icon.
