I don't see any way to create a background color for the text using the watermark filter.  That's why I've been using DynamicText, to set background color/alpha and padding.  Am I missing something?

Brian,

For what you are trying to do, you would be better served by the watermark filter. Here is an example:
melt colour:red -filter watermark:"+line1~line2~line3.txt" composite.progressive=1 producer.align=centre composite.valign=c composite.halign=c producer.fgcolour=blue


The "producer.*" properties are passed to a pango producer and the "composite.*" properties are passed to a composite transition.
