/* D95: the -mgfx budget (from boss.c's per-level memallocstringtable) is a
* byte count sized for N64 8-byte `Gfx` slots. On x86-64 a `Gfx` is 16
* bytes, so the same master display list needs 2x the bytes -- otherwise
* `gdl` (bumped with a bare `gdl++` by every render fn, no bounds check)
* marches past g_GfxBuffers[1]/[2], off the stage mempool, and eventually
* faults at the end of the 8 MB emulated DRAM (0x70800000) while writing a
* GBI command. Scale by sizeof(Gfx)/8. Vtx/Mtx are 16/64 bytes on both
* targets, so g_VtxBuffers is left alone. */
