461db47e87 geometrictransform: Adds rotate element
Adds a new rotate element to geometrictransform. It still
needs some work. But this is a good starting point.

Based on patch from Bert Douglas <bertd tplogic com>

0c0adffce7 geometrictransform: new filter "fisheye"
Ports gleffects "fisheye" filter to geometrictransform.
Fake fisheye lens filter. Somewhat empiric implementation because I
didn't find any good algorithm that does it with nice results.

9ee12f94de geometrictransform: new filter "mirror"
Ports gleffects "mirror" filter to geometrictransform.
Simple yet effective mirror effect, splits the image into halves and
reflect the first into the second.

5c4915d917 geometrictransform: new filter "square"
Ports gleffects "square" filter to geometrictransform.
Maps a region around the center into a zoomed square and smoothly get
back to normal zoom. With faces it makes a funny "cube-face" effect.

b7660b122c geometrictransform: New plugin for geometric transforms
Adds a new plugin that has elements that perform geometric
transformations to images. By geometric transformations I mean
that the operations are functions that given the output pixel
position, get the pixel position in the input image. This pixel
is then copied from input to output.

The gstgeometrictransform baseclass makes it easy to write
such elements. It boils down to write the mapping function
and exposing properties

Already added the first of the elements, 'pinch'. It's a common
effect in image editors, like gimp (distort -> pinch)
