#TTP 340962 - LIVE: RENDERING: Font Sample Parameter Behavior in MIC Created sub struct for UDEditorFontParameterValue to contain the font parameter fields. Removed font specific widget construction as it can now use the generic CreateParameterValueWidget function to build the UI. [CL 2238120 by Allan Bentham in Main branch]
