gdiplus: Create a GDI brush only when needed.

[Vincent Povirk]

Looks better.

Maybe create_gdi_logbrush should fall back to creating a solid brush,
so that pens with weird brushes set will do something vaguely
sensible. Eventually, we will want to use a different implementation
of pens that does not involve gdi32 in those cases.
