Rewrite and extend computer graphics notes to follow a more conventional style

[levyry]

This PR aims to rewrite the current computer graphics notes to follow a more conventional, textbook like style, similar to the official BSz1 and BSz2 notes, while also adding some quality of life features, such as:

• a preamble
• improved quizzes
• extra information and trivia
• references to the official youtube channel

Guidelines

• Use more admonitions
• Use inline mode less, or at least use \displaymode
• Use less lists and enumerations, use paragraphs instead

Progress

• rewrite notes
  • all chapters done (12/12)
  • improved images
  • improved quizzes
• add preamble
  • add youtube playlist link
• add common math terms page
• add custom admonitions
  • for definitions
  • for extra knowledge

In this first commit, I left a few comments about some stylistic choices. I plan on doing the rest of the files in a similar style, but this first commit mixes a few styles on purpose, to see which one the maintainers like more. After discussing which way to move forward, I will revise the first chapter to be stylistically homogeneous.

Cool idea!
The guidelines are great but should be executed carefully. For example paragraphs are great, but enumerations may help with memorizing the content.

In 1.md the admonitions are a bit too much for me personally. But these might actually help some people, so feel free to keep it as it is.

Jó az ötlet és tetszik az irány, viszont a honlapon breakel a formázás. A vscodeos extensionnel lehet jól néz ki, de az másik engine. Kérlek buildeld le és nézd meg, hogy élesben is jól néz-e ki!

This is something I have considered, and in my opinion, the main studying notes should be kept at least a bit separate from the "I already studied the material and I just want a quick refresher to cram stuff" type of notes. I don't have a really good solution to this, one idea I had was to include a "Review" section at the end, which would be a bullet point list of the most important topics of that chapter. I am open to other ideas though.

In 1.md the admonitions are a bit too much for me personally. But these might actually help some people, so feel free to keep it as it is.

I might tone them down a bit, this first commit was more about putting stuff out there and seeing what works and what doesn't. In the future I'll try to keep admonitions to mainly definitions and the like.

After this rewrite I was planning on opening a second PR in which I'd implement general QoL changes to the notes, such as:

• adding a preamble chapter, with general information about the course (mainly related to studying it, not administrative info), with a place for anyone to add their opinions in PR's
• adding a link to the official computer graphics video from the lecturer at the beginning of each chapter, so it's available to anyone easily
• adding higher quality pictures in some chapters
• adding a TL;DR at the end of each chapter before the quiz, which would contain the most important formulas and ideas from the chapter
• with permission, adding my own grafika-hf-template to the preamble, which I plan to maintain if the framework were to change again, and make platform independent
• adding a "common math terms" chapter, in which I would provide definitions, explanations and examples for certain terminology used in the material, such as: associative, commutative, algebra, orthogonal, normalized, unit vector, position vector, etc.

As these changes aren't strictly relevant to this PR, I won't include them here, but I would still appreciate some early feedback on these ideas, so they will have already been discussed a bit before opening the second PR.
