[Piglit] [PATCH] glean: remove line drawing code from fbo test

[Brian Paul]

The glean fbo test exercises rendering to 1D, 2D, 3D and cube images
attached to FBOs.  For the 1D texture case, the rendering is done with
a line, rather than a polygon.  Since the 1D image is one pixel high,
the slightest mis-rasterization of the line will cause it to be clipped
and the test to fail.

Just fall through to the polygon drawing code to avoid that issue.
Less code too.
