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)

shmpipe: Fix crash when sp_close_shm is called with self == NULL.
...
If sp_open_shm errors out trying to open a shm area, it would crash
when trying to free the area. The RETURN_ERROR macro calls
sp_shm_area_dec with self == NULL. sp_shm_area_dec calls
sp_shm_close, with self == NULL, which it then tries to access a
parameter of without checking. This patch checks to make sure
self != NULL before accessing that parameter.
