precision=double fixes

Added the ability to disable world coordinates for shaders.
Added the ability to fix the position of instances.
`ScopedPairIdConfig` is now a structure.
Added a class `ViewportToDebugContainerItem` for storing containers of the world and viewports.
Replaced `typedef` with `using`.
Fixed warnings about converting `double` to `float`.
