Add necessary build flags and switch from using a
GLES2 context to a GLES3 one.
This also enables building for OpenXR

This uses a similar multipass approach to blend shapes
as Godot 3.x, the major difference here is that we
need to convert the normals and tangents to octahedral
for rendering.
Skeletons work the same as the Vulkan renderer except the bones
are stored in a texture as they were in 3.x.
This includes collision (2D SDF, Box, Sphere, Heightmap),
attraction (Box, Sphere), and all sorting modes.
This does not include 3D SDF collisions, trails, or
manual emission.
GLAD 1 creates unusable loaders for EGL, while the newly released GLAD 2
does not, so for consistency I thought that it would be a good idea to
uniform things beforehand. While it had some API changes some renames
were all that was needed and everything works like before, at least on
the Wayland branch.
I've kept the structure identical, although this new generator has quite
a few hefty features, such as a single header mode.
I've also added GLAD to `thirdparty/README.md`, but I haven't specified
that in the commit title because it's a very small "fix".
Interleaving draw_rect calls with and without a texture forces every rect to
have its own draw call. In this case it meant that there is a draw call for every single
tile in the atlas. This change makes it so the renderer can batch draw calls
which reduced the draw call count by a factor of 512
- Removed empty paragraphs in XML.
- Consistently use bold style for "Example:", on a new line.
- Fix usage of `[code]` when hyperlinks could be used (`[member]`, `[constant]`).
- Fix invalid usage of backticks for inline code in BBCode.
- Fix some American/British English spelling inconsistencies.
- Other minor fixes spotted along the way, including typo fixes with codespell.
- Don't specify `@GlobalScope` for `enum` and `constant`.
This allows using texture_2d_get on all platforms which is needed for the get_image function
This commit also fixes some OpenGL warnings on the Web platform that came from attempting to map a buffer with zero length
This argument is now non optional, but this never hits the same bad access.
I voted to simplify the code here since the argument is never used optionally in our codebase.
