Improve the renderer selection framework. This framework has no UI, but it utilizes exportables and new choices can be hand crafted.

#844062: Turned the normal drag and drop editor into a renderer plugin, made the IPE part of it. Also some fairly serious code reorganization.

Deprecated panels_get_panels() function. This will be eventually disappear. Use panels_get_regions() instead.

logic with its old wrapper (panels_render_pane()) into a single method
on the renderer for readability.

encapsulated polymorphism (display renderer). Though the core effort
should probably employ top-level polymorphism, encapsulation is fine for
the current purposes, and makes backwards compat a LOT easier.

#612704 by c960657: panels_get_pane_content() inappropriately created a blank context when no contexts were available.

#624710: fix an old, old bug where the default empty context was not being appropriately wrapped in an array.

Break panels_node_content into a module + a .inc file to more clearly represent how content types can work in a module. Also fix several notices by providing defaults for the form.

Add a new directive to content types to allow fetching information about a single subtype (i.e, view, block) rather than all at once.

Introducing the new version of flexible which is both more powerful and comes with a javascripty visual layout designer. It is not yet flawless but it finally works well enough to commit. This commit REQUIRES the twin commit of ctools that is going in.

Improve styles and flexible layout with css caching and moving the rounded corner style fully into its sub directory.

Minor updates to stay up with ctools; remove deprecated panel_node_viwe task handler, as it will now always be panel_context

Some major restructuring, catching up to CTools. This is very much in process, there is a huge list of things that need to happen here still, but this may be checkpoint usable to the strong-stomached.

Changed post-arg context build check to be aware of the fact that we now use error codes for argument plugins, and it should only load add'l contextual data if the return is an object (aka, isn't numeric)

View panes display plugin. Note that this checkin may break a bunch of content types because I added $subtype to some content type declarations and need to go through all the content types and update the render and title functions.

plugin loading.

Original fix was made in version 1.1.2.47 of plugins.inc.

Templatize all panel layouts; give each layout its own directory for cleanliness. Slight improvement to the API needed for the move to work.

Initial D6 work -- this includes only panels.module stuff. Right now the drag & drop display editor works, layout, layout settings and render works. Special features such as cache and styles may or may not work.
