[Magnifier-76] Show for translated/scaled textview

In Ibb81fdc9d2ec8ba14914166e408c92a3aad7e312 we disabled the magnifier
for cases when the magnified TextView (or a view above it in the view
hierarchy) was matrix transformed (translated, scaled or rotated).
This CL reenables the magnifier for translated and scaled TextViews. The
translation case was already working.
