Update copyright statements to 2020 Happy new year to the wonderful Godot community! We're starting a new decade with a well-established, non-profit, free and open source game engine, and tons of further improvements in the pipeline from hundreds of contributors. Godot will keep getting better, and we're looking forward to all the games that the community will keep developing and releasing with it.

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.
