| tgt | The surface to use as the backing storage for this AttachmentDescriptor. |
| loadExistingContents | Whether to read in the existing contents of the surface when the RenderPass starts. |
| storeResults | Whether to store the rendering results of the attachment when the RenderPass ends. |
Binds this AttachmentDescriptor to the given target surface.
This method sets the backing storage of this AttachmentDescriptor to the given target surface.
If loadExistingContents is true, changes loadAction to RenderBufferStoreAction.Load unless the load action is already set to RenderBufferStoreAction.Clear, in which case this parameter is ignored.
If storeResults is true, changes storeAction to either RenderBufferStoreAction.Resolve or RenderBufferStoreAction.StoreAndResolve depending on whether ConfigureResolveTarget has also been called.
The format of the target surface must match with the format given in the constructor, and the target surface dimensions and sample count must match the values given in the RenderPass contructor.
