Note that I did not touch #borderWidth because it would bump to "2" far too quickly. We would need 1.5 but our rendering system does not allow that. :-)

Because the current rendering system does not support it.

Hm, #screenScaled etc. could improve the readability a bit, but they do not answer the question of which layers one should touch to configure dpi-sensitivity. Conceptionally, I would expect this to happen in the Canvas/drawing and the event-handling parts only, but unfortunately, Morphic and Point/Rectangle do not support sub-pixels for whatever reason ...

Well, I think that #screenUnscaled is a more elegant solution for the things happening in UserInterfaceTheme >> #fixFontsAndScaleAound: :-)

In Vivide, I added #scaleValueToDisplay on Integer and Point besides the already existing #scaleIconToDisplay on Form. Tobias (topa) suggested a different approach for DPI-awareness, that is, #screenScaled and #screenUnscaled -- which I did not fully understand yet.

A new version of Morphic was added to project The Inbox:

Honor hi-dpi settings for halo, window, and keyboard-focus indication borders.

Argh, this makes all these methods harder to read ... Did I patch the methods at the right abstraction level? Please review!
