Detailed Description

RenderBuffer encapsulates a GL renderbuffer (glGenRenderbuffers) used as a depth/stencil attachment in FrameBuffer. Tracks the storage format and dimensions so that copy semantics can recreate an equivalent renderbuffer without sharing the same GL object ID.

Copy semantics (deep copy): * A new renderbuffer is allocated with the same format and current size.

Move semantics: * Ownership is transferred; source rb_ID is zeroed.

Note:

GPU Resource Ownership: Owns rb_ID, released via glDeleteRenderbuffers in destructor.
