8c5360a559 geometrictransform: Adds prepare function and cleanup 
Adds a prepare function to make subclasses precalculate values
that will be used throughout the mapping functions.

Also adds a missing cleanup to fix a memleak

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)

b9decbb056 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.

e87cd0a29a shm: Add shm based sink and src 
These two elements (shmsink and shmsrc) communicate buffers using POSIX
shared memory. They also communicate the caps. The source currently acts as
a live source and ignores the timestamps coming from the sink. It also does
not transfer the tags.
