There was a problem hiding this comment.
Been a while since I wrote this in Bullet, but it looks ok. Did not test because I dont have master setup.
I only left a few comments about minor improvements.
Also, considering this algorithm traverses a heightmap that will never exceed the largest sizes an image can have, I'm not sure if using real_t for double is necessary, but it's probably good enough
Port raycast accelerator from Bullet's btHeightfieldTerrainShape.

Port raycast accelerator from Bullet's btHeightfieldTerrainShape (originally made by @Zylann).
Allows raycasting on heightmap shapes to have about the same performance in Godot Physics as in Bullet.
