Test for DrawText() with DT_CALCRECT bug

[Zach Gorman]

Changelog: Add test to demonstrate bug # 2329: DrawText() with DT_CALCRECT
incorrect in MM_HIENGLISH mapping mode.

This is a simple test that passes in Windows and fails in Wine. It shows
that in MM_HIENGLISH mapping mode, DrawText with DT_CALCRECT incorrectly
sets the rectangle bottom to a positive instead of negative integer. I am
hoping that someone with more experience on the wine GDI can correct the bug
itself.
