Text
A canvas can contain multiple text elements:
1) Static text
Text that remains the same for all images.
2) Fallback text
Used in place of dynamic text, when there is no dynamic text available.
3) Dynamic text
Dynamic text is used where available - i.e. for each recipient that has dynamic text associated with the merge tag.
Texts can be positioned forwards and backwards, to show in front of, or behind other elements on the canvas. They cannot be placed behind the background.
