openlayers WebGLVectorLayer point with cluster

Hello,

I haven't seen it in the examples, but I wanted to confirm with you that it is possible to create a WebGLVectorLayer point with a cluster and assign it a style function to generate different cluster styles depending on cluster size.

Thanks in advance,

A ol/source/Cluster is just a ol/Source/Vector with Point features that are generated on the fly. Though the style has to be https://openlayers.org/en/latest/apidoc/module-ol_style_flat.html#~FlatStyleLike for ol/layer/WebGLVector and text rendering is not implemented yet. https://github.com/openlayers/openlayers/blob/86ab34ac2469323e822ee51c7db9042b1da3a6e6/src/ol/layer/WebGLVector.js#L35

Thanks for your quick response @M393. OK, so I could apply different styles depending on cluster size, but text rendering is not possible. Do you know if there are plans to implement it anytime soon?
