Intros
Currently only .webp is supported for intros. You do not need RAWRBOX.RESOURCES as render will handle the file loading and presenting
Allows the user to add a custom splash screen / intro
render->addIntro("./content/my_intro.webp", <intro speed>, <cover>, <background color>);
You can then use onIntroCompleted to detect when the intro is completed
render->onIntroCompleted += [this]() {};
If no intro is being played or the screen is black, it means the update method is missing the rawrbox::Window::update() call.
You can also skip all intros by calling
render->skipIntros(true);
