// editor functions

// There are 3 potential brush handle lists
// 1. the list that contains brushes a plugin creates using CreateBrushHandle
// 2. the selected brush list (brushes the user has selected)
// 3. the active brush list (brushes in the map that are not selected)
// 
// In general, the same things can be done to brush handles (face manip, delete brushhandle, etc.. ) in each
// list. There are a few exceptions. 
// 1. You cannot commit a selected or active brush handle to the map. This is because it is already in the map. 
// 2. You cannot bind brush handles from the selected or active brush list to an entity. As of v1.0 of the plugins
// the only way for a plugin to create entities is to create a brush handles (or a list of handles) and then bind
// them to an entity. This will commit the brush(s) and/or the entities to the map as well.
// 
// To use the active or selected brush lists, you must first allocate them (which returns a count) and then
// release them when you are finish manipulating brushes in one of those lists.

// basically a plugin will hook the map load and save and will add the primitives to the map.. this will
// produce a temporary 'primitive' brush and the appropriate renderer will be called as well as the 
// edit handler (for edge drags, sizes, rotates, etc.. ) and the vertex maker will be called when vertex
// mode is attemped on the brush.. there will need to be a GetPrimitiveBounds callback in the edit handler
// so the brush can resize appropriately as needed.. this might be the plugins responsibility to set the 
// sibling brushes size.. it will then be the plugins responsibility to hook map save to save the primitives
// as the editor will discard any temp primitive brushes.. (there probably needs to be some kind of sanity check
