void ScreenMgr::Screen::SetOrthoProj() const {     StateMgr::Inst()->StateDisable(GL_DEPTH_TEST);    // Turn depth testing off     glMatrixMode(GL_PROJECTION);                    // Switch to projection mode     glPushMatrix();                                    // Save previous matrix which contains the settings for the perspective projection     glLoadIdentity();     glOrtho(0, width, 0, height, -1, 1);     glMatrixMode(GL_MODELVIEW); } void ScreenMgr::Screen::ResetPersProj() const {     glMatrixMode(GL_PROJECTION);     glPopMatrix();                                    // Pop the stack     glMatrixMode(GL_MODELVIEW);                        // Put us back in modelview mode                                                 StateMgr::Inst()->StateEnable(GL_DEPTH_TEST);    // Turn depth testing back on } /* when i want to do something with pixel coordinates, say render text, i make a call to the first function.  I do all of my text drawing, then make a call to this second function.  i was wondering if this constitutes as projection mode abuse or not. */

    nope :D
