+Sampler Views
+^^^^^^^^^^^^^
+
+These are the means to bind textures to shader stages. To create one, specify
+its format, swizzle and LOD range in sampler view template.
+
+If texture format is different than template format, it is said the texture
+is being cast to another format. Casting can be done only between compatible
+formats, that is formats that have matching component order and sizes.
+
+Swizzle fields specify they way in which fetched texel components are placed
+in the result register. For example, swizzle_r specifies what is going to be
+placed in destination register x (AKA r).
+
+first_level and last_level fields of sampler view template specify the LOD
+range the texture is going to be constrained to.
+
+* ``set_fragment_sampler_views`` binds an array of sampler views to
+  fragment shader stage. Every binding point acquires a reference
+  to a respective sampler view and releases a reference to the previous
+  sampler view.
+
+* ``set_vertex_sampler_views`` binds an array of sampler views to vertex
+  shader stage. Every binding point acquires a reference to a respective
+  sampler view and releases a reference to the previous sampler view.

+  to the texture. Format specified in template must be compatible
