Bring up layout tabs faster

This tip is especially helpful if you have large drawings with a lot of detail.

LAYOUTREGENCTL allows you to choose whether or not you regen when switching between tabs:

Controls the display behavior of how a layout acts when switching to it.

• 0 - Each time you switching to a layout tab, a regeneration occurs
• 1 - Model and the last layout tab is cached into memory
• 2 - Initial display of the tab is the only time that a regeneration occurs and any other time that the tab is activated it is read from cache
