- Adding in compatibility paths to support minimum per-vertex strides for vertex formats. OpenGL supports a minimum stride of 1 byte, in Metal, this minimum stride is 4 bytes. Meaing a vertex format must be atleast 4-bytes in size. - Replacing transform feedback compile-time check to conditional look-up, given TF is supported on macOS with Metal. - 3D texture size safety check added as a general capability, rather than being in the gl backend only. Also required for Metal. Authored by Apple: Michael Parkin-White Ref T96261 Reviewed By: fclem Maniphest Tasks: T96261 Differential Revision: https://developer.blender.org/D14510
