Add emacs mode-lines to ST sources To each .c and .h file, add: /* -*- mode: C; c-file-style: "gnu"; indent-tabs-mode: nil; -*- */ 'gnu' is the default anyways for Emacs, but indent-tabs-mode is not, so this sets things up to correspond to the policy of no-tabs. http://bugzilla.moblin.org/show_bug.cgi?id=6467

[St] Make allocation handling more consistent In StBin, StBoxLayout, and StTable, if a child has a potential allocation that is larger than its preferred size, we give it its preferred size instead. However, the corresponding get_preferred_height/width methods were not making the same assumption, which meant that if we had more width than the widget wanted, we would allocate it its preferred width, but with the height that corresponded to the larger width. Fix this by defining new helpers _st_actor_get_preferred_width() and _st_actor_get_preferred_height() and using them everywhere. Also, make StBin and StTable use _st_allocate_fill() rather than having nearly-identical duplicate copies of the code. https://bugzilla.gnome.org/show_bug.cgi?id=609848

st-theme-node-drawing: Don't create lots of one-shot materials A few places in st-theme-node-drawing create one-shot material, paint with it and then free it. This is suboptimal with current Cogl because it will end up compiling an ARBfp program just for that single paint and then it will throw it away when the material is destroyed. There is a new function in st-private.c called _st_create_texture_material. This creates a simple material for a texture based on a common parent material that points to a dummy texture. Any materials created with this function are likely to be able to share the same program unless the material is further modified to contain a different number of layers. It would be possible to use cogl_set_source_texture for this instead except that it's not possible to modify the material's color in that case so we couldn't render the texture with opacity. The corner textures are now stored as a handle to a material that references the texture rather than storing the texure directly. There is also a separate border_material member which always points to border_texture as the only layer. https://bugzilla.gnome.org/show_bug.cgi?id=633340
