I'm not sure about this one. Legacy apps (actually all apps) that size themselves by pixels might get their sizes rounded to something inappropriate if you used 'int gu'. Or do you mean 'float gu'? The latter would avoid the problem (despite lack of precision), but even better would be to not fix this bug at all.

Yes, float gu. The reason for that is restoring windows on a display with different density. If we recall a window from GU=8 on a GU=16 screen, it will not be what you wanted.

In this scenario apps get told what size (and scale) they are, not the other way around.
