CustomPassContext	ctx	Custom Pass Context.
RTHandle	source	Source to use for the downsample
RTHandle	destination	Destination buffer of the downsample
Vector4	sourceScaleBias	Scale and bias to apply when sampling the source buffer
Vector4	destScaleBias	Scale and bias to apply when writing into the destination buffer. It's scale is relative to the destination buffer, so if you want an half res downsampling into a fullres buffer you need to specify a scale of 0.5;0,5. If your buffer is already half res Then 1;1 scale works.
int	sourceMip	Source mip level to sample from.
int	destMip	Destination mip level to write to.
