//
// BaseVertexOffset is a signed quantity (INT) unlike the other parameters
// to this call which are DWORDS. This may appear strange. Why would
// the offset into the vertex buffer be negative? Clearly you cannot access
// vertex data before the start of the vertex buffer, and indeed, you never
// do. When you have a negative BaseVertexOffset you will also receive
// indices which are large enough that when applied to the start pointer
// (obtained from adding a negative BaseVertexOffset to the vertex data
// pointer) which fall within the correct range of the vertices in the
// actual vertex buffer, i.e., the indices "undo" any negative vertex offset
// and vertex accesses will end up being in the legal range for that vertex
// buffer.
//
// Hence, you must write your driver code with this in mind. For example,
// you can't assume that given an index i and with a current vertex buffer
// of size v:
//
// ((StartIndexOffset + i) >= 0) && ((StartIndexOffset + i) < v)
//
// Your code needs to take into account that your indices are not offsets
// from the start of the vertex buffer but rather from the start of the
// vertex buffer plus BaseVertexOffset and that furthermore BaseVertexOffset
// may be negative.

// The reason BaseVertexOffset can be negative is that it provides a
