* gdk/win32/gdkdrawable-win32.c (gdk_win32_draw_polygon,
gdk_win32_draw_segments, gdk_win32_draw_lines): We can calculate
the width and height of the bounding rectangle only after the
minumum x and y have been found, and need a separate loop for
it. Thanks to Bruce Hochstetler for providing a sample program
exhibiting the bug.
