Fully integrates CoglMaterial throughout the rest of Cogl This glues CoglMaterial in as the fundamental way that Cogl describes how to fill in geometry. It adds cogl_set_source (), which is used to set the material which will be used by all subsequent drawing functions It adds cogl_set_source_texture as a convenience for setting up a default material with a single texture layer, and cogl_set_source_color is now also a convenience for setting up a material with a solid fill. "drawing functions" include, cogl_rectangle, cogl_texture_rectangle, cogl_texture_multiple_rectangles, cogl_texture_polygon (though the cogl_texture_* funcs have been renamed; see below for details), cogl_path_fill/stroke and cogl_vertex_buffer_draw*. cogl_texture_rectangle, cogl_texture_multiple_rectangles and cogl_texture_polygon no longer take a texture handle; instead the current source material is referenced. The functions have also been renamed to: cogl_rectangle_with_texture_coords, cogl_rectangles_with_texture_coords and cogl_polygon respectivly. Most code that previously did: cogl_texture_rectangle (tex_handle, x, y,...); needs to be changed to now do: cogl_set_source_texture (tex_handle); cogl_rectangle_with_texture_coords (x, y,....); In the less likely case where you were blending your source texture with a color like: cogl_set_source_color4ub (r,g,b,a); /* where r,g,b,a isn't just white */ cogl_texture_rectangle (tex_handle, x, y,...); you will need your own material to do that: mat = cogl_material_new (); cogl_material_set_color4ub (r,g,b,a); cogl_material_set_layer (mat, 0, tex_handle)); cogl_set_source_material (mat); Code that uses the texture coordinates, 0, 0, 1, 1 don't need to use cog_rectangle_with_texure_coords since these are the coordinates that cogl_rectangle will use. For cogl_texture_polygon; as well as dropping the texture handle, the n_vertices and vertices arguments were transposed for consistency. So code previously written as: cogl_texture_polygon (tex_handle, 3, verts, TRUE); need to be written as: cogl_set_source_texture (tex_handle); cogl_polygon (verts, 3, TRUE); All of the unit tests have been updated to now use the material API and test-cogl-material has been renamed to test-cogl-multitexture since any textured quad is now technically a test of CoglMaterial but this test specifically creates a material with multiple texture layers. Note: The GLES backend has not been updated yet; that will be done in a following commit.

[cogl] Remove max_waste argument from Texture ctors The CoglTexture constructors expose the "max-waste" argument for controlling the maximum amount of wasted areas for slicing or, if set to -1, disables slicing. Slicing is really relevant only for large images that are never repeated, so it's a useful feature only in controlled use cases. Specifying the amount of wasted area is, on the other hand, just a way to mess up this feature; 99% the times, you either pull this number out of thin air, hoping it's right, or you try to do the right thing and you choose the wrong number anyway. Instead, we can use the CoglTextureFlags to control whether the texture should not be sliced (useful for Clutter-GST and for the texture-from-pixmap actors) and provide a reasonable value for enabling the slicing ourself. At some point, we might even provide a way to change the default at compile time or at run time, for particular platforms. Since max_waste is gone, the :tile-waste property of ClutterTexture becomes read-only, and it proxies the cogl_texture_get_max_waste() function. Inside Clutter, the only cases where the max_waste argument was not set to -1 are in the Pango glyph cache (which is a POT texture anyway) and inside the test cases where we want to force slicing; for the latter we can create larger textures that will be bigger than the threshold we set.
