Manage mapped memory (glMapBuffer) with std::vector

Question

it occurred to me that it would be a good idea to manage a range of mapped memory (from glMapBuffer) with a std::vector.

// map data to ptr
T* dataPtr = (T*)glMa

No, and for good reason. This code would never work. For example, you could alter the MapBuffer and break the size/capacity values inside the vector. You could push into the vector and cause an access violation/segmentation fault. You could cause a resize, destroying the buffer. And, fundamentally, if it's already within a contiguous array, what's the benefit? You could roll a custom container for fixed length arrays, I guess.

Especially! if you already have a pair of pointers to act like iterators.
