Yes, I agree that find_offset would be a useful method.
Regarding bug #1, the swap_buffers problem with glRasterPos being modified by
gl_draw on Mac OS X: Looking at the non-APPLE implementation(s) of gl_draw,
they appear to leave that state of glRasterPos alone, which is probably why

I have added files for two test programs that demonstrate the reported
Gl_Window bugs.

The Mac OS X Fl_Gl_Window implementation has a serious bug in the code for
Fl_Gl_Window::make_current when Fl_Windows are nested. The computation for the
x and y values of the xywh array passed to aglSetInteger(context_,
AGL_BUFFER_RECT, xywh) does not take this nesting into account, causing th
I have found two major bugs in the Mac OS X implementation of Fl_Gl_Window. I
will report the bugs in two separate postings.
The first bug occurs with overlays on Fl_Gl_Windows. If either the OpenGL view
transform or model transform are other than identity, then the code in
Fl_Gl_Window::swap
