optional nit: Do you anticipate using this function in code other than
PartialMagnificationController? If not, I would move the function there.

(I find these util files hurt readability. In particular, since there is no
class or namespace declaration here, it's hard to figure out which file contains
PaletteContainsPointInScreen by just looking at the call site.)

Yep, it will be used by the laser pointer.
