Bug #815 - Split up request, allocation, and paint box * clutter/clutter-actor.[ch]: Rework the size allocation, request and paint area. Now ::request_coords() is called ::allocate(), and ::query_coords() has been split into ::get_preferred_width() and ::get_preferred_height(). See the documentation and the layout test on how to implement a container and layout manager with the new API. (#915, based on a patch by Havoc Pennington, Lucas Rocha and Johan Bilien) * clutter/clutter-clone-texture.c: Port CloneTexture to the new size negotiation API; it just means forwarding the requests to the parent texture. * clutter/clutter-deprecated.h: Add deprecated and replaced API. * clutter/clutter-entry.c: Port Entry to the new size negotiation API. * clutter/clutter-group.c: Port Group to the new size negotiation API; the semantics of the Group actor do not change. * clutter/clutter-label.c: Port Label to the new size negotiation API, and vastly simplify the code. * clutter/clutter-main.[ch]: Add API for executing a relayout when needed. * clutter/clutter-private.h: Add new Stage private API. * clutter/clutter-rectangle.c: Update the get_abs_opacity() call to get_paint_opacity(). * clutter/clutter-stage.c: (clutter_stage_get_preferred_width), (clutter_stage_get_preferred_height), (clutter_stage_allocate), (clutter_stage_class_init): Port Stage to the new size negotiation API. * clutter/clutter-texture.c: Port Texture to the new size negotiation API. * clutter/clutter-types.h: Add ClutterRequestMode enumeration. * clutter/x11/clutter-stage-x11.c: Port the X11 stage implementation to the new size negotiation API. * tests/Makefile.am: Add the layout manager test case. * tests/test-opacity.c: Update. * tests/test-project.c: Update. * tests/test-layout.c: Test case for a layout manager implemented using the new size negotiation API; the layout manager handles both transformed and untransformed children.
