It is the same as windows 8 (scales). There are also different levels of
support, like dpi aware and also per monitor dpi aware.
High DPI support in the IDE is an ongoing issue with the latest releases.
It is much much better than what it was.
It just scales the control, you can check out the source code for what is
happening, just search for the DoAfterMonitorDpiChanged method.
Old versions of delphi with a DPI other than 96 will be horrible and
inconsistent with the presentation.
The per monitor support is interesting. Each control has a current dpi
property as you can't rely on Screen.PixelsPerInch anymore.
