Description
In vello_hybrid, image rendering is currently supported through an atlas texture, which requires uploading images into that atlas before they can be used. We’d like to extend this by enabling direct usage of external textures, allowing them to be sampled directly in addition to the atlas approach.
Our primary goal is to support rendering thousands of images efficiently, and the atlas remains a simple and robust choice for enabling this across native platforms and the web (webgpu and webgl2). Looking ahead, bindless resources appear to be the preferred path for native platforms, though this option is not available in webgl2.

Research direction
Start by tracing the vello_hybrid image-rendering and atlas-texture path. Compare the requirements for direct external textures across native platforms, WebGPU, and WebGL2; done means external textures can be sampled directly while atlas rendering remains supported.
