This is a continuation of an on-going work for 64-bit floating point builds, started in PR #7528. Covers physics, physics/joints and physics_2d code.
Also removed matrixToEulerXYZ function in favor of Basis::get_euler.
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer
with state-of-the-art rendering techniques tuned to work as low as middle
end handheld devices - without compromising with the possibilities given
for higher end desktop games of course. Great times ahead for the Godot
community and the gamers that will play our games!
