extension definition

Explanation: (1) An object module that can be dynamically added to a running system; often used as a synonym for kernel extension. (2) A feature of OpenGL that’s not part of the OpenGL core API and therefore not guaranteed to be supported by every implementation of OpenGL. The naming conventions used for extensions indicate how widely accepted the extension is. The name of an extension supported only by a specific company includes an abbreviation of the company name. If more then one company adopts the extension, the extension name is changed to include EXT instead of a company abbreviation. If the OpenGL Architecture Review Board approves an extension, the extension name changes to include ARB instead of EXT or a company abbreviation
