So I just realized that the SCI Studio VGA's SCI1 Pic editor has greyed out buttons for importing bitmaps and setting custom priority line positions (as well as rectangle and ellipse tools). I don't know how I missed this. None of them really work, though. I tried making a test build after enabling the buttons but the import function is seriously messed up. It puts a bunch of garbage on the picture instead of the actual image. I don't know if it's actually trying to draw it (SCI Companion style) or put the actual bitmap into the picture SCI1 style. I'm investigating what pushing this Import Bitmap window actually does and why it's screwing up....
I just wish I knew more about this. I notice that a few of the functions in Studio VGA fall back to SCI0 defaults even though there are SCI1 functions present. This could just be a matter of pointing events to the right function or adding a conditional statement somewhere in the source. Or it could be as easy as adding a simple flag or something somewhere. BC++ has a function to display "forms" of windows using its libraries that generate Windows(TM)-style...er...windows. Along with menus, tooltips, buttons, etc. You can look at all the buttons, edit their sizes, what they display, etc it's all very intuitive and point & click and you can go to the source for the function call that happens when a certain event takes place (like clicking on a button). This is all very interesting, I just wish I knew more about BC++.
