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 
Only one point is freed at a time, so pass by reference.

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.

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.

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.

Kp 62b58e9890 Move OGL to dxxsconf.h; rename to DXX_USE_OGL 
Rename symbol OGL to DXX_USE_OGL to show that it is a DXX
symbol, not one inherited from a library.  Move it to dxxsconf.h to
shorten the command line.

This is a mostly automated transform, but the changes to SConstruct were
manual.
