----------------------------------------------------------------------
This test checks all combinations of source and destination
blend factors for the GL_FUNC_ADD blend equation.  It operates
on all RGB or RGBA drawing surface configurations that support
the creation of windows.

Note that a common cause of failures for this test is small errors
introduced when an implementation scales color values incorrectly;
for example, converting an 8-bit color value to float by
dividing by 256 rather than 255, or computing a blending result
by shifting a double-width intermediate value rather than scaling
it.  Also, please note that the OpenGL spec requires that when
converting from floating-point colors to integer form, the result
must be rounded to the nearest integer, not truncated.
[1.2.1, 2.13.9]

The test reports two error measurements.  The first (readback) is
the error detected when reading back raw values that were written
to the framebuffer.  The error in this case should be very close
to zero, since the values are carefully constructed so that they
can be represented accurately in the framebuffer.  The second
(blending) is the error detected in the result of the blending
computation.  For the test to pass, these errors must both be
no greater than one least-significant bit in the framebuffer
representation of a color.

Note: RGB tolerance changed to 1.9
Note: Alpha tolerance changed to 2
