How to use monitor-scaling correctly?

[tmssngr]

I'm trying to catch up with SWT's changes in respect to monitor specific scaling, but my latest update broke our applications (using 4k monitor with 175% zoom on Windows 11).

Before c35c568:

After upgrading to c35c568:

The problems I see:

• images are either painted clipped or scaled causing blurred results
• lines are not drawn any more at exact pixel locations, so they appear blurred
• ovals are not drawn centered any more
• controls are slightly too small causing scrollbars to show up with 1 pixel to move horizontally

How we need to fix/workaround these problems in our code?
