If you refer to rotating around a arbitrary axis, you could just multiply your vertexs world matrix with the points world matrix.
then it becomes more of a local matrix.

but if you can, try to explain the situation and abit more about your problem,

Please specify whether you are talking about 2 or 3 dimensions, rotation around a point can be performed only in 2D, rotation in 3D is done around an axis.
You can not rotate around a point in 3D because there are infinite directions around it to represent axes.

That's not true at all! C++ doesn't require anywhere near the hand-eye coordination juggling requires. And with C++ after you slip and kill someone with the knife, you can reuse it for something else afterward. With actual knives, you have to get rid of the evidence.
