f1ced59ccb geometrictransform: rename gemetric math functions to have their symbols namespaced 
Otherwise those symbols can conflict with external libraries when
linking everything statically for mobile targets.

Use the gst_gm_ prefix, short for gst geometric math.

ae2231624c geometrictransform: Fix setting black background for AYUV buffers 
When the frame buffer is AYUV writing all zeros does not set it to
black, in YUV colorspace 0x10 is the black level for luminance and 0x80
is the black level for chrominance.

Fix setting the background to black when the out_frame format is AYUV;
in all the other supported formats zeroing the data with memset is still
the right thing to do.

7dd5b2002a geometrictransform: Prevent access to the transform map when it is null 
Check if the map doesn't exist when receiving a new caps and create
a new one. This prevents that the transform functions try to access
the map when it doesn't exist.

a45a1d70dd geometrictransform: Use explicit formats from gstvideo 
Use explicit format macros from gstvideo to avoid exposing
unsupported formats on template pads. Using the macros
also give us complete caps (width/height/framerate).

And add support for AYUV.

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)
