A lightweight templateable WPF shape

I'm using ellipses and other shapes as onscreen markers, I would like others to be able to change these visuals using templates.

Conditional Inclusion/Exclusion of Data Members Inside Class Templates

I want to optimize my Vector and Matrix classes (which are class templates to be exact) using SIMD instructions and compiler intrinsics.

C++ templates have been a blessing in my everyday work because of its power. But one cannot ignore the (very very very very long) compilation time that results from the heavy use of templates (hello meta-programming and Boost libraries).
