I have a real pickle in trying to debug Pd. Namely, when I grep-ed
every single instance of pdtk_canvas_getscroll and commented it
out, it still gets invoked somehow and I am at a loss how. I know
it occurs as many times as there are objects selected that have
been moved (so it is definitely per-object)

Use <execinfo.h>'s backtrace() so that sys_vgui prints the name of
the calling function just before each line is printed while in -d 1
mode.

That sounds useful, do you have an example of how that you could share?
