/* The glext.h guard was renamed in 2018, but some software which
|
||
|
|
* includes their own copy of the GL headers (such as qt) might have
|
||
|
|
* older version which use the old guard. This would result in the
|
||
|
|
* header being included again (and symbols redefined).
|
||
|
|
*
|
||
|
|
* To avoid this, we define the "old" guard if the "new" guard is
|
||
|
|
* defined.*/
