Parameters

src	The resource to read the data from.
size	Size in bytes of the data to be retrieved from the ComputeBuffer or GraphicsBuffer.
offset	Offset in bytes in the ComputeBuffer or GraphicsBuffer.
mipIndex	The index of the mipmap to be fetched.
dstFormat	The target TextureFormat of the data. Conversion will happen automatically if format is different from the format stored on GPU.
x	Starting X coordinate in pixels of the Texture data to be fetched.
y	Starting Y coordinate in pixels of the Texture data to be fetched.
z	Start Z coordinate in pixels for the Texture3D being fetched. Index of Start layer for TextureCube, Texture2DArray and TextureCubeArray being fetched.
depth	Depth in pixels for Texture3D being fetched. Number of layers for TextureCube, TextureArray and TextureCubeArray.
width	Width in pixels of the Texture data to be fetched.
height	Height in pixels of the Texture data to be fetched.
callback	A delegate System.Action called once the request is fullfilled. The done request is passed as parameter to the System.Action.
