Add Lock to Focal Plane to Blur VFX

This optn works only in camera view and defines the blur factor depending of location of the object in depth of field. If the object is on a location inside near and far depth of filed values, the blur is disabled.

Refactor VFX code

Make code more consistent and clear to understand.

Allow zero samples for VFX Blur

When the number of samples is set to zero, the blur is dissabled, but this can be used to get effects animating the samples parameter.

If the zero is not a valid value, it is impossible to disable the blur with only this parameter.

Fix reproject error drawing lines

The reproject was done two times and must be done only once.

Cleanup redundant variable

Fix errors after merge
