...custom on-top rendering (or a callback to it)...

Awesome, I'll look into that! It sounds like interacting with BearLib's layers would be more difficult and involved?

And what you're saying is the OpenGL I use will need to be functions available below version 2? I'm curious as to why you chose such an older version to work with - I admittedly don't know that much about the different OpenGL versions.

Don't suppose there's any easy way to getting at the OpenGL so I can implement my own additional graphical effects on top of what's rendered, is there? Or would I have to fork, modify, and compile the library on my own?

Indeed, there is currently no way to do custom rendering. Reliable custom rendering requires support and guarantees from the library, which is far from its focus of abstracting the output.

That said, I do try to make the library capable to perform various tricks without diving into relatively low-level stuff. For example, a circling orb may be implemented via overlayed tile with offset. Take a look at "Extended 1: basics" (lines 42-49) entry in SampleOmni, those circling characters are flying around one spot.

OK, that makes sense. I'm considering grabbing the source code of the library, and trying to modify it just so I can slide some of my own draw calls in before BearLibTerminal refreshes.
Any suggestions on where to start with that (or if it's even feasible)?

I've been working on a project using this library (very happy with it!), and I'm planning for the future - specifically, if I want to do more advanced graphics than just what is included in the library.

For example, if I wanted a little orb to be circling around a character, I might use BearLibTerminal for placing all the tiles and sprites, but then do some graphics coding of my own for the orbiting orb.

Edit:
Project is in C++, by the way.
