> Roman, Mike, * can the MSI itself be made dpi aware?

MSI *is* DPI-aware. And all its dimensions are, in fact, in special units
related to a font size scaled to the screen resolution [1].

It is obvious that our installer does follow the resolution properly on the
screenshot, if you look at the top banner with "6".

The problem here seems to be because of using ICO images for these specific
problematic places (and Icon type in Control.idt), not BMP (and Bitmap type).

The Icon type [2] has some bits that might be related, namely FixedSize and
IconSize, and maybe we can just modify those, and not change the type.
