draws all loaded widgets of a Bangle.js 2 without clearing the background
By default, the Bangle.js 2 runtime clears the whole widget stripes on the top (or bottom) of its display, as soon as any widget has been loaded into that area. On displays with a structured background (such as a bitmap) this behaviour hides anything underneath these stripes.
For that reason, this module modifies the widget drawing method such that the background is not cleared - leaving it up to the widget to take care of that itself (which most widgets do).
Just "require" this module before any widgets are drawn - that's all:
