Looks like the KallistiOS Dreamcast SDK disables double support
by default: 495e77fd60/environ_dreamcast.sh (L16)
We don't really need doubles in this code.
The one place where we might have needed them is the SMK video
decoder, handled in a separate PR.
SMK format actually defines frame durations in units that are 0.01ms:
91e732bb69/src/SmackerDecoder.cpp (L329-L334)
That's great because it means we can do everything using integer math.
Stairs can have the same `TileProperties` as floors but do not
always follor the same graphics layout as floors, so we shouldn't
apply optimizations to them.
The only floors affected seem to be:
1. Caves: tile 48 sub-tile 171 frame 461 (TileProperties: None)
2. Hell: tile 46 sub-tile 141 frame 386 (TileProperties: BlocksMissile)
Note that the few broken in pixels in caves are actually incorrectly
attributed to the non-Solid tile, really they should be part of the
solid tile 49.
As there doesn't seem to be a quick and easy way to check if a frame
is part of Stairs, we add a check for BlocksMissile tile property
instead.
This fixes Hell but isn't enough to fix Caves.
To fix Caves, we then add a `BlocksMissile` flag to the broken sub-tile.
`dev.display.grid()` previously tanked the FPS even on my beefy machine.
It is now much faster.
I've also noticed that the grid is glitchy when but this is also the
case before this PR.
Fix a bug that caused two-handed items not to able to be equipped
if there was an item in the right hand, but not in the left one
and also there wasn't enough space to place the right item TWO times.
This was unintended, obviously, the right item should only be checked for once.
