We lose about ~500ms showing the splash screen, because VCL must access many
configuration files (VCL.xcu,FontSubstitution.xcu,Common.xcu,...).
There is a special window class called IntroWindow which should prevent this,
but it doesn't work.
See the following stack, where a PostUserEvent needs a default window and
creates a "real" window which starts the configuration access.

We have to show the splash screen as soon as possible, so this is big
performance hit for this special target.
