ImGUI is a "Bloat-free Immediate Mode Graphical User interface for C++ with minimal dependencies"- meaning we can manipulate it from c++ directly
I have some issues with keyboard input being captured as well (I don't have backspace!! Or arrow keys !!!!!) as well as the mouse movement being forgeted but overall it's good
atm I'm doing this by intercepting the call to SwapBuffers (same thing as BLBrowser) and drawing right before it with OpenGL functions stolen from the game directly- this theoretically will allow me to draw on top of it, but no promises! :D
