Move rendering into st-theme-node-drawing.c The idea behind this move is that we have a lot more control over rendering if StWidget isn't a big pile of actors, and things are more efficient. https://bugzilla.gnome.org/show_bug.cgi?id=607500

[StThemeNode] Add helper method to get the paint allocation StThemeNodes may have properties - namely shadows - which paint outside an actor's allocation. This is not a problem unless drawing is redirected to an offscreen buffer, in which case the actually painted size is needed in advance when setting up the buffer. Add a convenience method to calculate an allocation large enough to paint the node. https://bugzilla.gnome.org/show_bug.cgi?id=619025

[StThemeNode] Make shadow helper functions semi-public Move shadow helper functions from st-theme-node-drawing to st-private to make them available to widgets which want to add shadows to internal actors. Also add a new helper function for creating the shadow material from a ClutterActor. https://bugzilla.gnome.org/show_bug.cgi?id=624384

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

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

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.

/* Rough notes about the relationship of borders and backgrounds in CSS3;

*
* - Things are drawn in 4 layers, from the bottom:
* Background color
* Background image
* Border color or border image
* Content
* - The background color, gradient and image extend to and are clipped by
* the edge of the border area, so will be rounded if the border is
* rounded. (CSS3 background-clip property modifies this)
* - The border image replaces what would normally be drawn by the border
* - The border image is not clipped by a rounded border-radius
* - The border radius rounds the background even if the border is
* zero width or a border image is being used.
*
* Deviations from the above as implemented here:
* - Nonuniform border widths combined with a non-zero border radius result
* in the border radius being ignored
* - The combination of border image and a non-zero border radius is
* not supported; the background color will be drawn with square
* corners.
* - The combination of border image and a background gradient is not
* supported; the background will be drawn as a solid color
* - The background image is drawn above the border color or image,
* not below it.
* - We don't clip the background image to the (rounded) border area.
*
* The first three allow us to always draw with no more than a single
* border_image and a single background image above it.

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.
