GAMGI requires a 3-button mouse to work properly, as the mouse buttons are one of the ways to rotate, move and scale objects. With a 2-button mouse, users can configure the button order for example to discard scale and use move and rotate modes only.
GAMGI should run with any version of Glib/Gtk 1, but does not even compile with Glib/Gtk 2. GAMGI should run with any version of Mesa or OpenGL, though a recent release is recomended, due to some bugs. GAMGI should run with any version of Gtkglarea 1. GAMGI should run with any version of Expat. GAMGI should run with any version of Freetype 2, but does not even compile with Freetype 1.
