Bug 1358: 'Honor' SWT's projection of High-DPI Scaling (Reading hidden pixel dimensions)

Christian reported this bug and described multiple pathways.

This change usese the following:
- access to getClientAreaInPixels w/ fallback of
- DPIUtil.autoScaleUp(getClientArea())

I hardly have tested this on Linux/GTK, even though I use a High DPI monitor,
maybe just because of it and Eclipse _poor_ state of proper UI presentation.

Christian: Please test this .. if buggy, reopen quick for release 2.4.0

SWT/GTK High-DPI is a PIA:
- GDK_SCALE renders offscreen and scales the image (wow & ugly)
- GDK_DPI_SCALE works at least on the fonts properly
- swt.autoScale is pretty much like: What will be scaled?
  It scales some icons in Eclipse, not fonts and result in Eclipse
  looks horrible.

Maybe I just made this patch to vent about this poor state of things.

Notable: KDE looks great and uses DPI, firefox some GDK_DPI_SCALE equivalent (OK)

One also wonders why there is only a single scale dimension, where DPI differs x/y!
But enough of my rant :)
