- maybe force the window to be a specific resolution
- border decorations for shapes
- remove the hardcoded 1920 and 1080 values when applying relative pixel constraints
and replace them with the screen's currently active resolution

text rendering improvements
  - [x] unicode support (allows for non-ascii characters)
  - [x] atlas texture for text glyphs (this means we only load in one texture for all text)

  - SDF generation allowing for better text scaling (slower but visually better)
    - SDF is too slow if we want to support unicode. it's acceptably fast for ascii only though.
    - An alternative is to use MSDF at a much lower pixel height (e.g 16) which results in
      better scaling than SDF (almost perfect) and is fast enough to include unicode.
    - Another alternative is using a pre-baked SDF texture atlas. This is the fastest
      but it's also the least flexible because we can't load arbitrary fonts
    - Maybe also rendering text as vector using bezier curves. Sounds like a lot of work though.

      Will probably end up using MSDF (if I can get it to work with C lol)

  - instanced rendering for text (this means we only have to do one draw call for all text)
