This should be a no-op in kernel-mode!

Are we sure we want to do this in kernel mode...? Why would we need Bezier curve drawing in the kernel?

It was a sanity check to make sure floats weren't being wacky, I forgot to remove it

We should be able to use a ReadOnlySpan to store the bytes directly, without the need for Base64-decoding. For example:

Fonts were made awhile before we could, and base64 works for now so.. 🤷♂️ I never bothered changing it since it worked, but if you think readonlyspan works, be my guest!
