Remarks
Dependency property identifier field: BorderThicknessProperty
This property only affects a control whose template uses the BorderThickness property as a parameter. On other controls, this property has no impact.
Non-integral values of a Thickness for BorderThickness are technically permitted, but should generally be avoided. Non-integral values will introduce subpixel rendering, which can possibly result in antialiasing artifacts.
