    /** Text batches are mix between how mesh and line batches work.
     * - They still keep track of various draw groups each with it's material
     * - However that material is not really being used, but rather the properies are copied over to the batch fp32 data texture
     * - For filtering we cheat and use `SpeckleTextColoredMaterial` only to store the gradient/ramp texture + gradient indices for each text in the batch
     * - The color from the gradient/ramp texture will be used only if the gradient index > 0, otherwise the regular color will be used
     * - The gradient index is stored in each text object in it's `userData` and written to the 27'th float in the batch data texture, where the shader reads if from
     * - Even if, the **text batch does not use the materials in it's draw groups**, it emulates the behavior as if it would
