Sorry to resurrect this thread, but I could now teach a class on using custom graphics and compiling custom graphic themes in Studio. You were right, native resolution graphics are completely out the window.

Smart graphics are the only way to go. It takes a lot of time and patience, but I am now working directly for an integrator who wants something completely unique for all of his clients.

I am doing a full blown custom floorplan for zone select / overview, and whole house audio manager where you can select one or more zones, then the audio source select appears, and after that you have volume control and presets. All of the icons will populate dynamically via code. Client wants a quick way to have full control of audio in every zone. He does a lot of entertaining.

If anyone is interested, I could share some screenshots.
