PhysicalDeviceMeshShaderFeaturesNV
Fields taskShader :: Bool `taskShader` indicates whether the task shader stage is supported. meshShader :: Bool `meshShader` indicates whether the mesh shader stage is supported.

DrawMeshTasksIndirectCommandNV
Fields taskCount :: Word32 `taskCount` is the number of local workgroups to dispatch in the X dimension. Y and Z dimension are implicitly set to one. `taskCount` must be less than or equal to `PhysicalDeviceMeshShaderPropertiesNV`::`maxDrawMeshTasksCount` firstTask :: Word32 `firstTask` is the X component of the first workgroup ID.
