<brief_description>
Framebuffer pass attachment description (used by [RenderingDevice]).
</brief_description>
<description>
This class contains the list of attachment descriptions for a framebuffer pass. Each points with an index to a previously supplied list of texture attachments.
Multipass framebuffers can optimize some configurations in mobile. On desktop, they provide little to no advantage.
This object is used by [RenderingDevice].
