gstglshadervariables and gstglshaderfilter

gst/gl/gstglfiltershader.c:

Implements a plugin allowing:

- To load a simple fragment shader filter and to set uniform variables through
object properties.

- To replace the shader or to set uniform variables during pipeline execution
through object properties.

usage: glshader location=<shader_file> preset=<variables_file> vars=<variables>


gst-libs/gst/gl/gstglshadervariables.c:

Implements a parser for GLSL variable definitions that can also be used for
other gstglfilters (eg: to set a convolution kernel or a threshold value)
