[Feature] Differents preloader types : Logo, HTML, Inline SVG...

[fchaussin]

As discuss on Slack, It could be great to handle different preloader types. By adding a constant parameter type like this:

page.preloader.type=[ logo | html | inline_svg | ... ]

• logo will be the default value. Specified as it already is in: page.preloader.logo

I'm not sure how to implement page.preloader.html and page.preloader.svg, since it need to stay sanitized (that means all css scripts and all that stuff will be remove automaticly). Is wrapping HTML with Typoscript in the setup a good convention for the bootstrap_package project? Maybe with a Fluid Partial? Any suggestion to handle this properly?

For a memo here a commetn from Ben Kott, while talking about this on Slack:

Benjamin Kott [15 h 51] i can think about this for a bit - currently do not have a clear answer to that. problem is - rendering svgs inline is a pretty easy task. the package is already doing this a lot for all kinds of icons you can set.

but all svgs will be inserted sanitized inline - that means all css scripts and all that stuff will be remove automaticly or atleast script stuff providing full control with an option to allow any kind of html in there could be an option because the user opted to take full security control here still unsure about this one whats the best way to go type could be an option to switch between that modes i need to play around with this idea for a bit - currently in preperations for LTS so could take a while
