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.

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

On some embedded systems, sqrt() is not supported in the shader,
use the actual value of sqrt(2) instead.
