Update copyright statements to 2021 Happy new year to the wonderful Godot community! 2020 has been a tough year for most of us personally, but a good year for Godot development nonetheless with a huge amount of work done towards Godot 4.0 and great improvements backported to the long-lived 3.2 branch. We've had close to 400 contributors to engine code this year, authoring near 7,000 commit! (And that's only for the `master` branch and for the engine code, there's a lot more when counting docs, demos and other first-party repos.) Here's to a great year 2021 for all Godot users 🎆

Perfect FreeType-based outlines for DynamicFonts - Implement outlines based on FreeType Stroker API. This allows artifact-free results, similar to what you will see in Web or any text editing tools. Outline is a part of DynamicFont rather than Label, because outlines have to be baked into the font's atlas. Font has a default outline_color and a Label can specify font_outline_modulator that will be multiplied with the Font's color to get the final result. - draw_char now has to be called twice to fully render a text - first with p_outline == true for each character and then with p_outline == false for each character. - Number of draw-calls is reduced from 5 to 2 per outlined character. - Overall cleanup of DynamicFont code, extracted duplicated code pieces into separate methods. - The change is backward-compatible - Labels still have outline properties that work exactly as they worked before. Closes #16279.

I can open your eyes Make you see your bad indent Force you to respect the style The core devs agreed upon A whole new world A new fantastic code format A de facto standard With some sugar Enforced with clang-format A whole new world A dazzling style we all dreamed of And when we read it through It's crystal clear That now we're in a whole new world of code

Exposed RenderingDevice to script API Also added an easier way to load native GLSL shaders. Extras: Had to fix no-cache for subresources in resource loader, it was not properly working, making shaders not properly reload. Note: The precommit hooks are broken because they don't seem to support enums from one class being used in another. Feel free to fix this after merging this PR.
