Multires fast navigate in object mode

At the moment, quick navigation works on one mesh only in sculpt mode.

I suggest adding this feature to object mode for all meshes with the Multires modifier, which will help increase performance with minimal programmer effort.

When creating highly detailed characters, the main load falls on the video card, secondly on RAM.

With the current implementation, the 4060ti starts to slow down at around 70 million polygons, making it difficult to create highly detailed characters. The artist has to reduce the number of divisions in object mode. This prevents him from seeing the whole picture.
