You need to create a geometric pen (otherwise linesize is always fixed to 1). Using ExtCreatePen()

Set the line width.

Pen style will be dashed/hatched or whatever

Set the foreground mix mode (using SetROP2() in GDI) to do an XOR of the pen with the foreground

Draw the lines

Draw overthem with an XOR mode again to delete them non-destructively
