Interpolation causes bluriness of fine detail
Hello
I use the "Magnifier" desktop effect primarily for two things:
1. When taking a screenshot with Spectacle, to perfectly align the rectangular
selection.
2. When examining or taking a screenshot of pixel artifacts in imaging
software.
In both cases, what I really need to see is an zoom without interpolation, just
the view scaled by 400% or so. The magnifier seems to be hardcoded to use
linear or cubic interpolation which destroys detail.
Please add an option to the Magnifier to not interpolate/use nearest-neighbor
interpolation, so that pixels stay sharp when enlarged.
