-Samplers are used to access texture data in shaders. To use a sampler with a
-texture, bind it to the same texture unit. Each texture has a default sampler
-which is used if no external sampler is bound.
-
-A texture is generally rendered at a size that's either smaller or larger than
-its native size, so that the texture coordinates do not exactly correspond to
-the texels of the texture. The kind of filtering used, if any, is determined
-by the minification and magnification filter parameters. The default is LINEAR
-for magnification and NEAREST_MIPMAP_LINEAR for minification.
-
-If texture coordinates fall outside of the principal range of the texture,
-wrapping is applied. The default for all directions is REPEAT.
+Stores settings affecting how values are obtained from textures in a shader.
+Samplers are always used together with textures.
+
+Texture coordinates are first transformed according to the wrap mode for each
+axis. One or more texel values are then read and combined according to the
+filtering mode.
