/** @file tex-border-1.c
 *
 * 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.).
