  * Notes:
  * - vgmstream may dynamically allocate stuff as needed (not too much beyond some setup buffers, but varies per format)

+ * - some details described in the API may not happen at the moment (they are defined for future internal changes)
  * - main reason it uses the slighly long-winded libvgmstream_* names is that internals use the vgmstream_* 'namespace'
  * - c-strings should be in UTF-8

  * - vgmstream's features are mostly stable, but this API may be tweaked from time to time (check API_VERSION)
