Use OpenCL

  OpenCL is an acronym for Open Computing Language (see Wikipedia). This option tries to improve the processing speed of certain operations by using the GPU (graphic processing unit) instead of the CPU.

  | Warning
  This is a very experimental feature that is known to crash often! Only enable this if you intend to work on improving it and don't forget that you enabled it.

Experimental

N-Point Deformation Tool

  This tool lets you create a rubber-like deformation of the image using points.

Seamless Clone Tool
