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

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.

3ba30d42a4 gl: use gles2 shaders everywhere
This effectively limits a glfilter subclass to be > GL(ES) 2.0.
rather than a possible GL 1.4.
