2 points can be moved

just 6 base points with 2 sliders
window can be resized (the figure stays in center position)
morphing figure

on moving c- and f-point square morphs to other figure, that connects
base 6 points
slae is working

fractional linear transformations for pixels are realised
optimized gauss

without new matrix on each iterations
and without extra copying operations
1 stage of morphing

the image can be morphed
top half
the layer filter
nearest type
added bottom half of earth

crrect moving C and F points morphs the image
(mirroring is not correct)
