32ba17cd0f Use gst_element_class_set_static_metadata()
where possible. Avoids some string copies. Also re-indent
some stuff. Also some indent fixes here and there.

a00614064b geometrictransform: adds some properties to base class
Adds a property to select what to do with pixels that are mapped out of
edges: ignore, clamp or wrap.

to keep common properties code for filters that operate on
a circular area.

Small optimization by precalculating the center of the effect,
also use newly added _CAST macro.

525aae23dc geometrictransform: Rename some variables for clarity
Renames some variables and adds a minimum doc to the
mapping function for a little clarity.

Also uses gstvideo functions for the row and pixel strides
instead of hardcoded values

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)
