- gpu.c sends gr_set_depth_triangle only while a PGXP renderer feature is
on (gl_renderer_pgxp_render_wanted): no RTH_DEPTH per triangle otherwise.
- The SZ rides in the textured vertex's unused colour alpha, so TEXV stays
26 floats for every title.
- gl_renderer_set_pgxp_depth / _threshold / pgxp_render_stats sync with a
live render thread (GL_RT_SYNC) like their neighbours.
- A depth-mode change is its own batch-break reason (7); batch_diag returns
all eight reasons.
- Smooth-motion in-between frames replay RTH_DEPTH and test depth from
their own clear; gl_frame_gen_test gains a PGXP pass (overlapping 3D
triangles out of painter order) where the in-between frame must match
the real one.
