Block a given window
PtBlockedList_t *PtBlockWindow( PtWidget_t *window, unsigned short cursor, PgColor_t cursor_color );

PtBlockWindow() blocks the given window (if not NULL).
If cursor isn't zero, this function sets the window's cursor to that value and its cursor color to cursor_color (if different from Pg_TRANSPARENT). Ph_CURSOR_NOINPUT is a typical choice for the cursor; for a list of the other cursors, see <photon/PhCursor.h>.
A pointer to a control structure that can be passed to PtUnblockWindows() to undo the changes, or NULL if an error occurred or there was nothing to do.
