[cogl/wip/rib/master-next: 33/35] texture: Make CoglTextureRectangle experimentally public



commit 4a0379d80f3773397876dbcaa8693a59049dc88b

    texture: Make CoglTextureRectangle experimentally public
    
    This exposes CoglTextureRectangle in the experimental cogl 2.0 api. For
    now we just expose a single constructor;
    cogl_texture_rectangle_new_with_size() but we can add more later.
    
    This is part of going work to improve our texture apis with more
    emphasis on providing low-level access to the varying semantics of
    different texture types understood by the gpu instead of only trying to
    present a lowest common denominator api.
    
    CoglTextureRectangle is notably useful for never being restricted to
    power of two sizes and for being sampled with non-normalized texture
    coordinates which can be convenient for use a lookup tables in glsl due
    to not needing separate uniforms for mapping normalized coordinates to
    texels. Unlike CoglTexture2D though rectangle textures can't have a
    mipmap and they only support the _CLAMP_TO_EDGE wrap mode.
    
    Applications wanting to use CoglTextureRectangle should first check
    cogl_has_feature (COGL_FEATURE_ID_TEXTURE_RECTANGLE).

+ * SECTION:cogl-texture-rectangle
+ * @short_description: Functions for creating and manipulating rectangle
+ *                     textures for use with non-normalized coordinates.
+ *
+ * These functions allow low-level "rectangle" textures to be allocated.
+ * These textures are never constrained to power-of-two sizes but they
+ * also don't support having a mipmap and can only be wrapped with
+ * %COGL_PIPELINE_WRAP_MODE_CLAMP_TO_EDGE.
+ *
+ * The most notable difference between rectangle textures and 2D
+ * textures is that rectangle textures are sampled using un-normalized
+ * texture coordinates, so instead of using coordinates (0,0) and
+ * (1,1) to map to the top-left and bottom right corners of the
+ * texture you would instead use (0,0) and (width,height).
+ *
+ * The use of non-normalized coordinates can be particularly
+ * convenient when writing glsl shaders that use a texture as a lookup
+ * table since you don't need to upload separate uniforms to map
+ * normalized coordinates to texels.
+ *
+ * If you want to sample from a rectangle texture from GLSL you should
+ * use the sampler2DRect sampler type.
+ *
+ * Applications wanting to use #CoglTextureRectangle should first check
+ * for the %COGL_FEATURE_ID_TEXTURE_RECTANGLE feature using
+ * cogl_has_feature().

+ * @height: The texture height to allocate
+ * @internal_format: The desired internal texture format
+ * @error: An optional GError pointer for reporting exceptions
+ *
+ * Allocates a new #CoglRectangle texture with a given @width, @height
+ * and @internal_format. This texture is a low-level texture that
+ * the GPU can sample from directly unlike high-level textures such
+ * as #CoglTexture2DSliced and #CoglAtlasTexture.
+ *
+ * <note>If you want to sample from a rectangle texture from GLSL you

+ * first check for the %COGL_FEATURE_ID_TEXTURE_RECTANGLE feature
+ * using cogl_has_feature().</note>
