We may want to migrate this to 1 file per monster but for now the
migration is as close to the hard-coded version as possible.
Sprites that are used by multiple monsters are only loaded from disk
once.
For monsters with the same sprite, load the sprite from the file system only once.
Example:
```
VERBOSE: Loaded monster graphics: falspear\phall 452 KiB x1
VERBOSE: Loaded monster graphics: skelbow\sklbw 618 KiB x1
VERBOSE: Loaded monster graphics: skelsd\sklsr 610 KiB x1
VERBOSE: Loaded monster graphics: goatbow\goatb 832 KiB x1
VERBOSE: Loaded monster graphics: bat\bat 282 KiB x2 <-- here we only load the sprite once
VERBOSE: Loaded monster graphics: rhino\rhino 1306 KiB x1
VERBOSE: Loaded monster graphics: golem\golem 298 KiB x1
VERBOSE: Total monster graphics: 4401 KiB 4684 KiB
```
Here, the bat sprite will be loaded from the MPQ only once.
For the second sprite, we simply clone the first sprite before applying TRNs.
This also reduces the size of `MonsterData` from 88 bytes to 80.
When we migrate monster data to a TSV, the sprite IDs can be generated automatically at load time.
This has little or no effect on the optimized build
but significantly improves performance of the headless debug build
`timedemo_test` on my machine goes from 3s to 2s.
Original Blizzard encoder is slightly less optimal than our encoder.
While size in RAM in less of a concern for the non-`UNPACKED_MPQS`
build, smaller files are faster to render.
Savings for unpacked and minified MPQs:
* diabdat.mpq: 918,311 bytes.
* hellfire.mpq: 313,882 bytes.
Example player graphics (note that only a few are loaded at any given time for single player):
* diabdat/plrgfx/warrior/: 366,564 bytes.
Example monster graphics savings:
* diabdat/monsters/skelbow: 5,391 bytes.
Based on the implementation from https://github.com/diasurgical/devilutionx-graphics-tools/pull/6
* Only play the The Chamber of Bone lore for the reader
* Only play dialog for the player who is having the conversation
* Allow rock quest when skipping to level 5
Done with the following script:
```ruby
Dir["Source/**/*.{h,c,cc,cpp,hpp}"].each do |path|
v = File.read(path)
next if !v.include?("uint32_t") || v.include?("cstdint")
lines = v.lines
line_num = if lines[2].start_with?(" *")
lines.index { |l| l.start_with?(" */") } + 3
else
3
end
lines.insert(line_num, "#include <cstdint>\n")
File.write(path, lines.join(""))
end
```
then fixed-up manually
