[1/2] gdiplus: Partial implementation of GdipCreateHatchBrush

[Chris Wulff]

This supports the most basic hatch brushes that map to the standard
HS_xxx types. The remaining brushes are created as just a solid color.
It also doesn't do much useful with the background color at this point.

Note that a number of other functions won't do anything useful if passed
a hatch brush yet either (pens or drawing text for example.)
