Function: skinVertex2D()

skinVertex2D(vx, vy, idx, wgt, base, skinMats, out, o): void

Linear-blend-skin one vertex against up to 4 bone skinning matrices.

skinMats[boneIdx] is rootLocalNow[bone] · invBind[bone]. The skinned position is the weighted sum of the bind vertex pushed through each influencing bone's skinning matrix. Weights are assumed normalized (unused slots weight 0). Writes the packed [x,y] result into out at offset o.
