As most, I have indeed not encountered collisions, yet, not that I could remember anything serious (I remember a macro called sth like WIN32_NO_MINMAX though).

A name like "Rectangle" will only have collisions if there is a C file that simultaneously includes headers from two distinct libraries that define that name, which frankly is very unlikely and very easy to work around. As long as you don't define a silly constructor that creates a symbol Rectangle::Rectangle(float, float, float, float) or whatever, there will not even be linker collisions when distinct parts of a software include distinct definitions of the Rectangle name.

Nevertheless, I simply name my types like "VxRect" or whatever in case they are supposed to be consumed by other components. Much better than Vx::Rect or even Company::Math::Types::Rect, isn't it?
