[racket] Using a splash screen with GRacket

Wow, that is even better than that!
Digging a bit further, it uses the framework/splash module,
which does everything I wanted (and more), even with the gauge
that progresses automatically, and it works like a charm out of the box!
Awesome.

And it is so simple to use:

<<<
#lang racket/base

(require racket/runtime-path
         (for-syntax racket/base) ; for build-path for runtime-path
         framework/splash
         )

(define-runtime-path splash-path
  (build-path "img" "splash.png"))

(start-splash splash-path "My Project" 200) ; frame name, default width

(dynamic-require "my-project.rkt" #f)

(shutdown-splash)
(close-splash)
>>>

(no need for runtime-path if the application is not
intended for distribution)

Maybe this could be documented?
