Detailed Description
QComponent to issue work for the compute shader on GPU
A Qt3DRender::QComputeCommand is used to issue work for the compute shader. The compute shader is specified in the QMaterial component of the same entity the QComputeCommand is added to. The workGroupX, workGroupY and workGroupZ properties specify the work group sizes for the compute shader invocation. Qt3DRender::QDispatchCompute node needs to be present in the FrameGraph to actually issue the commands.
