Notes
~~~~~
* All but the last used function (which should be Destroy) must use /NOUNLOAD so the image window won't be destroyed before it should.
* This plugin requires NSIS 2.0b4 and above.
* This plugin requires NSIS 2.42 and above.
* Do not call SetBg (which creates the window) from a section or a function called by a section.
* Never use /NOUNLOAD in .onInstSuccess and .onInstFailed. Failing to do so will cause the installer to crash.
This means you should not call Destroy from .onInstSuccess or .onInstFailed.
