-Since we defined a `varying` called `vTexCoord` in the vertex shader, we can now use it in the fragment shader as well. Here is a simple fragment shader that maps the x value to the red channel and the y value to the blue channel. Note that while `vTexCoord` is defined *per vertex* in the vertex shader, its value is defined *per pixel* in the fragment shader. To get the per-pixel value, WebGL smoothly interpolates between the per-vertex values on each face.
