# dispatch offsets to the functions that request that their offsets

- # To bring some sanity to the generated offsets, we group all

- # their functions in order. The groups are:
- #
- # 1. Core GL versions, sorted by version number.
- # 2. ARB extensions, sorted by extension number.
- # 3. Non-ARB extensions, sorted by extension number.
- # 4. Un-numbered, non-ARB extensions, sorted by extension name.
