// This file implements GlowGetProcAddress for every supported platform. The
|
|
// correct version is chosen automatically based on build tags:
|
|
//
|
|
// windows: WGL
|
|
// darwin: CGL
|
|
// linux freebsd: GLX
|
|
//
|
|
// Use of EGL instead of the platform's default (listed above) is made possible
|
|
// via the "egl" build tag.
|
|
//
|
|
// It is also possible to install your own function outside this package for
|
|
// retrieving OpenGL function pointers, to do this see InitWithProcAddrFunc.
