Kp f3d4dff941 Use enum class for clipping_code 
Adjust code_window_point to use the same masks as clipping_code.
Previously, it had top and bottom swapped.  However, since its output
was only ever compared for equality to 0, this transposition should not
affect the observable behavior.

Kp ad8f970bf6 Pass g3s_point & to free_temp_point

Kp 23315ebec2 Fix SDL-only g3_draw_sphere overflow test 
PF_OVERFLOW is part of p3_flags, not p3_codes.  Testing p3_codes meant
that the disk would be drawn when CC_OFF_RIGHT was unset.  This seems
unlikely to be what was intended, so fix the mismatch by switching to
use p3_flags instead of switching the symbolic constant.

Kp fa0d57961d Use runtime check for instance_stack overrun 
Replace assert with std::array<>::at(), so that an exception will be
thrown if the array bound is exceeded.

Kp 5d12f62d77 Omit p3_{u,v,l} from OpenGL builds 
These are write-only for OpenGL.  All reads are in SDL-only code.
Remove them to save 3 ints of space in every g3s_point.

For each link given as http://, verify that the site is accessible over
https:// and, if so, switch to it.  These domains were converted:

Kp 88430e8946 Require vms_angvec &for g3_start_instance_angles 
Only one caller exists, and that caller alway passes a non-nullptr
value.  Switch to a reference and remove the unused special case to
handle a nullptr input.

Kp 1831148092 Split g3_start_instance_matrix usage 
Most uses pass an orientation matrix.  All sites are deterministic about
whether a matrix is passed.  Make the matrix mandatory for sites that
passed it, and split out a separate version of g3_start_instance_matrix
for the 2 sites which do not provide orientation.

Kp b65b6339f4 Make g3_draw_sphere pnt argument const (for OGL only) 
SDL still needs to modify it, so use alias type `cg3s_point`, which is
`const g3s_point` in OGL and `g3s_point` in SDL.
