+ *
+ * Tests that the texture border color on a GL_RGBA texture is sampled
+ * correctly.
+ *
+ * This is intended to be the first test in a series.  Other tests
+ * that could be used are behavior of sampling texture border color
+ * for GL_RGB textures, and sampling the border color depending on the
+ * texture format (gen5 Intel hardware and up stores format-dependent
+ * border colors.).
