Description
Current blend modes do not work as expected with Transparent canvases (RGBA format) - resulting in rendering artifacts like this: https://github.com/playcanvas/engine/issues/2740
It is proposed that blend modes are adjusted to work with Transparent canvases when a project uses Transparent canvases where possible - and any blend modes that do not work are made known to developers in our documentation.

Research direction
Start by reproducing the rendering artifacts with an RGBA transparent canvas and read the linked issue #2740 for the existing behavior. Done means blend modes work where possible for transparent canvases, while modes that remain incompatible are identified in the project documentation.
