// 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). //
