class TPoint


TPoint

TPoint implements a 2D screen (device) point (see also TPoints).

Don't add in dictionary since that will add a virtual table pointer
and that will destroy the data layout of an array of TPoint's which
should match the layout of an array of XPoint's (so no extra copying
needs to be done in the X11 drawing routines).
