19 // TPoint implements a 2D screen (device) point (see also TPoints). //
20 // //
21 // Don't add in dictionary since that will add a virtual table pointer //
22 // and that will destroy the data layout of an array of TPoint's which //
23 // should match the layout of an array of XPoint's (so no extra copying //
24 // needs to be done in the X11 drawing routines). //
