Edit Background dialog

This pop-over aids customisation of main view backgrounds:

• Color. A standard trio of colour controls allow setting of $MapBackgroundColor. This forms the main background colour of main views.
• Pattern. A list of static patterns is used to set $MapBackgroundPattern.
• Color. A standard trio of colour controls allow setting of $MapBackgroundAccentColor. This is used as the accent colour in the background if a pattern is set.
• Fill. A texture list allows setting of $MapBackgroundFill, using a fill texture instead of a pattern or plain background.
  • Opacity. Sets the fill opacity ($MapBackgroundFillOpacity).
• Use Inherited settings. Restore the current background to document default settings.
• Save Settings As Default. This does the reverse of the above and uses the current background settings to set them as the document default settings.
