Fix for benign UBsan signed-integer-overflow complaints.
...
When counting nl and nc, the nnz is optionally also counted when in sparse mode. However, the functions mj_nl and mj_nc unconditionally counts nnz into a temporary accumulator, then only afterwards check whether the output nnz pointer is NULL.
When not in sparse mode, ten_J_rownnz does not get initialized by mj_tendon, however mj_nl and mj_nc are accumulating potentially spurious data from ten_J_rownnz into the temporary accumulator. While the spurious result eventually gets discarded, UBsan nevertheless detects an integer overflow in the temporary accumulator.

Add orthographic cameras.
...
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.
