💭 thought (non-blocking): This means we support at most 2B Gaussians. We should probably define our own integer type for this, because someday we will want to increase this limit.

Basically, we want to protect ourselves from the future need to increase the number of gaussians we support.
For image sizes, I don't see this being as risky because images tend to be in the thousands of pixels in each dimension. But we are already talking about billions of gaussians. So we don't want to hard code uint32_t everywhere. (Not to mention we may want sizes to be signed.)
