The spinner used for the DecimalUpDown and other controls uses glyphs that appear to be pixelated. I understand this was probably done to avoid anti-aliasing. However, in high DPI, it looks terrible as it appears to be in low resolution.
I've come up with my own solution by replacing the template for the ButtonSpinner, but it would be nice if this were to be integrated into the toolkit itself.
[Here's](https://github.com/picoe/Eto/blob/b05a65675ef1e5f1190b8de521fc7804f6e903dc/Source/Eto.Wpf/themes/wpftoolkit/ButtonSpinner.xaml) my modifications. It uses half pixel positioning so that it looks beautiful on both normal and high DPI displays.
