Liquify effect

The Liquify effect lets you push, pull, rotate, enlarge and shrink areas in a layer. Several Liquify tools distort the brush
area when you hold down the mouse button or drag. The distortion is concentrated at the center of the brush area,
and the effect intensifies as you hold down the mouse button or repeatedly drag over an area.
You can limit the area of a layer you distort using Freeze Area Mask. Use the Reconstruction mode to lessen or undo
distortions you've created.
The Liquify effect can extend beyond the boundaries of the target layer. This is useful when the target layer is smaller
than the composition.
This effect works with 8-bpc and 16-bpc color.
