675415bf2e gl: try to use highp precision where supported 
The use of mediump as a specifier in GLSL shaders will have limited
resolution and when used as texture coordinates may become inaccurate
over texture sizes of 1024.

b3d8e09839 glfilter: rewrite subclasses for filter_texture() occuring on GL thread 
There's no need for the jump to an extra thread in most cases, especially
when relying solely on a shader to render.  We can use the provided
render_to_target() functions to simplify filter writing.

8a92c66440 gleffects: fix little rectangle that appears at the center of squeeze and tunnel effects 
These two shader will calculate the vector length and use it as denominator.
But length could be zero which will cause undefine behaviour. Add protection for
this condition

d8c710d143 gleffects: identity: add the shader to the hash table 
So that we don't recreate it every frame and leak memory.

3fb60ac10c gleffects: fix gleffects fisheye shader compile error 
On some embedded systems, sqrt() is not supported in the shader,
use the actual value of sqrt(2) instead.

f688a8f0b2 glshader: port to using GstGLSLStage objects for string management 
A GstGLShader is now simply a collection of stages that are
compiled and linked together into a program.  The uniform/attribute
interface has remained the same.
