| 17 | // The purpose of the "class" is to provide access to extensions
|
|---|
| 18 | // without having to go through the hassle of aquiring them
|
|---|
| 19 | // in various places. They are defined as "extern" so that a
|
|---|
| 20 | // single function pointer is kept around, ie. this file can
|
|---|
| 21 | // be included in multiple files. The "glue" class should be
|
|---|
| 22 | // created right after the gl window is created.
|
|---|
| 23 | //
|
|---|
| 24 | // NOTE: Many of the extensions defined by this header will require
|
|---|
| 25 | // "exparamental" drivers from the chip/card manufacurer. If an
|
|---|
| 26 | // extension that you want is not detected, this is probably why.
