Label Halo, Outline, and Shadow do not work properly when using GDI+
If Labeling is set up to use GDI Plus, the font enhancement features (Halo, Outline, and Shadow) are not sized properly to fill the background. Note that these features do work properly if UseGdiPlus is set to False.
The TextRenderingHint is now automatically selected to satisfy this condition as long as GlobalSettings.AutoChooseRenderingHintForLabels = true, which is the default.
Any options that utilize the GraphicsPath (Shadowing, Halo, and Outline) require the Text Rendering Hint set to Anti-aliasing. Additionally, the GraphicsPath font size is in 'em's rather than Points, and requires conversion based on the current pixel density (DPI).
