Description

I'm sure this usecase is very esoteric, but I'm using egui with pixels and I wanted to put egui objects on the same screen location as objects I'm drawing on the pixel buffer, but to do that I need some way of going from pixel positions to window positions, and surprisingly there doesn't seem to be a way right now, even though there is a way to go from window position to pixel position via window_pos_to_pixel. Even without a crazy usecase like that, there are probably other scenarios where this would be something you want.

Contributor guide

Research direction
