With the switch to array textures, we lost wasm support.

There seem to be several separate issues:

  1. When the number of tiles in a tileset is either 1 or divisible by 6, the texture is treated as a cubemap and tiles show up at all.

gfx-rs/wgpu#2161

  1. Some other mysterious issue, which results in tiles showing up black

There might be wgpu bug with copy_texture_to_texture and arrays on webgl

I was unable to dig up a relevant issue for that one in the wgpu tracker

  1. We are limited to 256 tiles in a tileset due to texture dimension limits in wgpu.

This may have been fixed/mitigated by bevyengine/bevy#3452
