README

This is a fork of github.com/go-gl/gl/v2.1/gl with the below patch. This is now modified manually.

The original version is generated from github.com/hajimehoshi/glow's nocgo branch. This enables to remove dependencies on Cgo on Windows.

Now we are working on committing this 'no-cgo' change to the official gl package. See https://github.com/go-gl/glow/pull/102.

Context is a context for OpenGL (ES) functions.

Context is basically the same as gomobile's gl.Context. See https://pkg.go.dev/golang.org/x/mobile/gl#Context
