Detailed Description

The GlsMimicGroup class provides a way to group objects that change infrequently into a single textured polygon such that performance is increased due to not having to render the objects every frame. Instead, since all of the objects in the group are replaced with a single texture, performance is saved by updating the texture ONLY through handling a display event of name "MimicGroupUpdate". Whenever an object placed in this group is modified, you must write code to emit a "MimicGroupUpdate" ObjectEvent so that any changes made to its appearance will be reflected in the rendered texture.

For example: EmitObjectEvent( objectThatChanged, "MimicGroupUpdate" );

Picking and event handling for objects within the GlsMimicGroup work the same as for a regular Group, so it can contain interactive objects such as buttons, switches, etc. The GlsMimicGroup will only redraw the texture when it receives a "MimicGroupUpdate" ObjectEvent so you must write code to emit these events whenever a press, toggle, etc. affect the appearance of the object.

The GlsMimicGroup can contain 2D or 3D objects. All of these objects will be replaced with a 2D texture polygon so the GlsMimicGroup is best suited for use with panels that are mostly 2D. The GlsMimicGroup can also be useful with a collection of 3D objects as long as the GlsMimicGroup remains screen-aligned.

On older hardware that does not support the render-to-texture capabilities required by the GlsMimicGroup, the GlsMimicGroup will fall-back to rendering like a regular Group.
