Fix dotted line drawing for GDI device driver
When GDI device driver draws a dotted line, it also clip the line
into the device context's bound before drawing. This CL includes
a couple fixes:
-- When this driver is used for EMF drawing, the drawing is not
bound to the device context so clipping is not needed;
-- Transformation needs to be applied before clipping since the
transformation may move the line into the bound;
-- While checking for out-of-bound flags, bit operations are needed
to make sure the discarded line is completely out of bound, not
partially inside the bound;
