Type Alias rerun::external::re_renderer::DepthOffset

pub type DepthOffset = i16;

Depth offset used to resolve z-fighting between 2D primitives.

Zero means no offset. Higher values push an object towards the viewer, lower away from the viewer. Depth offsets are applied in the shader as-late as possible.

Implementation notes:

WebGPU provides a per-pipeline depth bias which would be optimal for this. However, this would require us to create a new pipeline for every new offset! Instead, we do manual offsetting in the vertex shader. This is more error prone but very dynamic!

Shaders typically pass in a f32 for easy of use and speed (no unpacking or expensive integer math required) This value is 16 bit to ensure that it is correctly represented in any case and allow packing if necessary.
