The "Set canvas" effect only allows to set a transparent/color filled background to the source image. We need an effect to allow specifying another image as background of the source image being processed (aka "Underlay").
Proposed resolution

mondrakeLooked a bit at this, and I think it's better to have a separate image effect to deal with it. The "Set canvas" effect has options for sizing and defining the background color that would be confusing if we try to keep also adding an image as background in the same effect.
What I fancy here is the 'opposite' of the "Watermark" effect - which allows to overlay a selected image on the source one. With "Background" effect, we would overlay the source image on a selected one.

mondrakeSame consideration as per #2655044: Add "Text overlay" image effect:
a) we're still in alpha
b) better have this in and address any bugs from reports, than waiting for reviews :(
Committed, now I'll go for alpha2
