Saran Tunyasuvunakool b362cb4972 Expose a handle for the Python viewer. 
This change also requires user scripts to explicitly synchronize changes to physics state to the viewer. The Simulate class was reconfigured so that certain UI events are handled during this sync operation, outside of the render loop on the main thread. These correspond to operations that require access to the full mjModel/mjData.

To support other, more interactive operations (e.g. camera movements), a new mjvSceneState struct is introduced which captures only the portion of the physics state required for scene re-rendering. The mjvSceneState is updated from mjModel/mjData during the viewer sync operation, and is significantly cheaper than a full mj_copyModel and mj_copyData.

Fixes https://github.com/deepmind/mujoco/issues/796

Kyle Bayes fe3dccfd1d Add a new plugin / extension mechanism called a resource provider along with retrofitting VFS on top of it. 
A resource provider provides a mechanism for MuJoCo to read from filesystems other than the OS filesystem or the Virtual File System (VFS).

Add -Wgnu-empty-initializer to Clang builds to catch this issue in the future. Initialising arrays with empty braces is not part of the C standard and fails on MSVC. This commit should catch the issue earlier by detecting it in Clang.

Yuval Tassa fe18e58ad2 Rendering of mjGEOM_LINE respects size[0] (width argument of mjv_makeconnector), denominated in pixels. 
- Before this change, line width was hardcoded to 3 pixels and the width argument of mjv_makeConnector was ignored.
- After this change, the width argument is respected and interpreted in units of pixel. The non-standard width unit is ok since lines can only be drawn programmatically.

Yuval Tassa 7542c90cd2 Improved behaviour of mouse-spring interactions. 
Also:

- Renamed recently introduced `mjvPerturb` member `reflocalpos` -> `refselpos` and corrected docstring.
- Added `mjvPerturb.localmass`: body spatial inertia at selection point.
- Removed `const` qualifier to `mjData` argument of `mjv_initPerturb()`, to facilitate spatial inertia computation.
- Improved `mj_Object{Velocity, Acceleration}` docstrings, clarifying that rotational velocities precede linear velocities.
- Removed redundant const qualifiers from non pointer arguments to `mju_dot` and `mju_writeNumBytes`.
