Description

So I just bought myself a funky windows tablet with retina like display (2k), when opening my Eto app with embedded webview my fonts look really ugly because it looks like they have been enlarged (by some unknown process) on the very high dpi display and the anti-aliasing is not working very well.

When I open the exact same webpage in IE (on the same pc) the fonts all look crystal clear.

Somewhere along the chain, the embedded IE is trying to scale up the font sizes and not doing a very good job..

Very strange.

Research direction
Investigate how Eto's WebView control handles high DPI scaling on Windows. Look at the Windows platform specific implementation (e.g., Eto.WinForms or Eto.Wpf) for WebView, particularly how font sizes are set. Check if there are any DPI awareness flags or scaling transformations applied. Also review comments in the issue for any debugging steps or potential fixes mentioned. Reproduce the issue on a high DPI Windows tablet to identify the exact rendering pipeline causing the font enlargement.
