A pack entry is keyed (texture, palette), so a draw whose CLUT ships no file
falls back to the original low-res texture even when the pack plainly has the
right IMAGE -- the texture hash identifies it, only the colour is unknown.
On an exact-key miss we now borrow any palette variant of the same texture for
its shape and take the colour from the live CLUT in the shader. REPL_FS gains
the VRAM usampler (on unit 1; unit 0 already holds the replacement image, and
sharing it would have the sampler read the pack PNG as if it were VRAM) and
reads the first non-zero palette entry as the ink. STP comes from that live
entry too, since a different CLUT may set the bit differently and reading it
off the stale image would blend the glyph wrongly. Alpha still decides the
cutout: that is the SHAPE, and the pack is the authority on it.
The gate is a property of the DATA, not a list of texture hashes we happen to
know are fonts: recolour only where the pack image has a single ink colour, so
there is no colour structure to flatten. image_is_mask computes it once at
decode. Multi-colour images decline and fall through unchanged, counted in
repl_multicol.
Also adds repl_calls / repl_nocontain / repl_notex, because "hit + miss" could
not distinguish "the pack has no image for this texture" from "no upload backs
this primitive", and those want opposite fixes. That distinction is what showed
the fallback does not fire on the WipEout 3 title screen at all -- every draw
there already hits its exact key -- so the substitution path is byte-identical
where it does not apply, and the blocky title-screen text has some other cause.
In gameplay the misses are overwhelmingly repl_notex: textures with no pack
entry of any palette, which recolour cannot help.
