I'm thinking along the lines of something that's more code and less
XML; a separate GUI plugin that implements a DSP plugin's custom
widgets on top of a simple canvas style API.
High level rendering API:
* Blit images (files specified in the XML)
* ???
Mid level:
* Lines
* Filled rectangles
* Filled polygons
* ???
Low level:
* Pixel access via RGBA buffer (auto conversion)
"Direct" rendering:
* Fast pixel access using screen format
(The last two methods are essentially the same; you avoid conversion
by using the screen's pixel format directly. If you don't the API
implementation will do conversion when refreshing the canvas.)
