I just thought it would be a good idea to mention somewhere that in this day and age of high-resolution displays (HiDPI), one digital pixel is not always one physical pixel. It can be 4 physical pixels, 9 physical pixels, etc. But it can also be somewhere in-between pixels, by which I mean something equivalent to a fractional scale factor, such as 1.5. I’m not exactly certain how the latter would work, but I would assume it would somehow involve “merging” pixels.
It would be nice if Redox (OrbTK?) had support for such things.
And, of course, vector graphics support would be nice too; it would perhaps make a high-resolution UI both easier to resize and look ‘smoother’ (if it’s all implemented, of course).
