Also, when a mesh has both an octree and a bvh, render only the octree.

This prevents the taxels from being occluded by the convex hull for meshes that do not provide face connectivity.

These flexes use only 24 DOFs (3 per vertex of the bounding box), while colliding with the full high resolution mesh.
On an 8x8x8 cube, the performance using DOFs at all vertices is
```
Simulation time : 18.74 s
Steps per second : 533
Realtime factor : 0.53 x
Time per step : 1874.4 µs
Contacts per step : 114.88
Constraints per step : 3322.51
Degrees of freedom : 1536
```
With the new implementation, it is the following:
```
Simulation time : 1.82 s
Steps per second : 5507
Realtime factor : 5.51 x
Time per step : 181.6 µs
Contacts per step : 38.84
Constraints per step : 155.36
Degrees of freedom : 24

Prior to commit 3f855f32d9, calling `mjv_updateScene` and `mjv_updateSceneFromState` on an "empty" `mjData` (one without a buffer but where all sizes are also zero) was a valid operation. The `mj_markStack` call requires free stack space, so a call to `mjv_addGeoms` on an empty `mjData` results in a stack overflow whenever `mjVIS_TENDON` is enabled.
Fixes#2305.

These functions names and argument ordering are more consistent with the rest of the API.

Orthographic cameras are specified by setting the `orthographic` attribute of the `<camera>` element. The `fovy` attribute is still used to specify the field-of-view, but its semantic is different for orthographic cameras. For orthographic cameras, the field-of-view is expressed in units of length, rather than degrees.
Other related changes:
* Fix bug in the ordering of `cam_xxx` elements in `mjModel`.
* Make camera visualization translucent only when the frustum is visualized.
* Added a button to `simulate` to toggle between perspective and orthographic free cameras.

Added `option-actuatorgroupdisable` attribute and associated `mjOption.disableactuator` integer bitfield, used to disable sets of actuators at runtime according to their group.
- The first 6 actuator groups are toggleable in the `simulate` viewer.
- Minor refactor and cleanup of actuator documentation.
