Copy subset of data into the currently bound vertex-buffer-data object
target -- the symbolic constant indicating which buffer type is intended
offset -- offset from beginning of buffer at which to copy bytes
size -- the count-in-bytes of the array (if an int/long), if None,
calculate size from data, if an array and data is None, use as
data (i.e. the parameter can be omitted and calculated)
data -- data-pointer to be used, may be None to initialize without
copying over a data-set
Note that if size is not an int/long it is considered to be data
*iff* data is None
