(Semi)transparent background in theme overrides at each render

[dkaraush]

I thought that it'll be great to make semitransparent editor, but it seems there is no support for now: I suppose that is lack of clearRect and using fillRect firstly.

How to reproduce: set theme of Primrose instance to have .regular.backColor be rgba(255, 255, 255, 0.5).

I see two ways to solve it: simply put clearRect or add event preupdate (or prerender), that will be fired before render happens, so I can make clearRect on my own.

Let me know if I need to provide more detailed example.

I see, the background needs to always be cleared, even when it's filled, because using a semi-transparent fill color will eventually saturate to completely opaque.

I see no problem with always calling clearRect first, and then only conditionally calling fillRect.

Hello, so glad you fixed this so fast, 3 hours, I didn't expect this :)

Well, when you don't have any external dependencies in a project, it's pretty easy to pick up where you left off :)
