// This class provides abstractions for receiving and using resources from other
// modules/threads/processes. It abstracts away GL textures vs GpuMemoryBuffers
// vs software bitmaps behind a single ResourceId so that code in common can
// hold onto ResourceIds, as long as the code using them knows the correct type.
// It accepts as input TransferableResources which it holds internally, tracks
// state on, and exposes as a ResourceId.
//
// The resource's underlying type is accessed through locks that help to
// scope and safeguard correct usage with DCHECKs.
//
// This class is not thread-safe and can only be called from the thread it was
// created on.
