Tek 2465 emulator

Hey y'all,

I'm writing an emulator for the venerable Tek 2465 oscilloscope https://w140.com/tekwiki/wiki/2465.
See https://github.com/sigurasg/mame/tree/tek2465 for the sources, such as they are to this point.
There's sufficient hardware emulated now that it's working to the point where the emulator
  1. passes most of the power-on self tests,
  2. renders the on-screen-display,
  3. shows the front-panel LED status, and
  4. can be interacted with through some temporary, awful keyboard mappings.
I'm thinking next up is to sketch the front panel in an SVG, and then to map the FP LEDs, screen and controls onto the SVG.

Now, I'm a total MAME n00b, both as a user and as a developer, so I'd love some pointers and/or suggestions.
  1. Where do I find a good example where there are on-screen controls and display on top of an SVG?
  2. The scope has a bunch of rotary controls, some discrete (VOLTS/DIV, SEC/DIV) and others that are potentiometers. I haven't figured a good way to represent rotary on-screen controls in MAME - what am I missing?
