I created my own theme from scratch so I can use my Aleera graphics (currently for RTI, Leviton / Bitwise, and ProControl to build templates in VTPro-e.

Basically, I had to figure out how to import them (pretty easy), how to build an image map (not too bad), them bring that into a new style.

Creating my own 9-Slice attributes to apply to different buttons was a chore, and I missed assigning them to a style category after about a dozen compile / tests.

I also had to figure out how to assign them in Control Styles as well. Once I got a single button to scale properly, I built the rest and started creating pages with all of the blank buttons and started placing my icon / overlays on everything in VTP.
