from Go 1.9 and earlier, use the cftype or jni rewrites in the Go fix tool:

	go tool fix -r cftype <pkg>
	go tool fix -r jni <pkg>

It will replace nil with 0 in the appropriate places.

The EGLDisplay case was introduced in Go 1.12. Use the egl rewrite
to auto-update code from Go 1.11 and earlier:

	go tool fix -r egl <pkg>

The EGLConfig case was introduced in Go 1.15. Use the eglconf rewrite

	"os"
	"sync/atomic"
	"time"

Open a web browser displaying trace:
	go tool trace [flags] [pkg.test] trace.out

Generate a pprof-like profile from the trace:
    go tool trace -pprof=TYPE [pkg.test] trace.out

[pkg.test] argument is required for traces produced by Go 1.6 and below.
