I choose a line primitve since using a 1D texture, but certainly could
use a 1D texture on a rectangle.
If using a rectangle then the test becomes basically window size
independent (except likely really tiny windows).
I think if the line were drawn aligned to the viewport axis then it
would also make the test independent of window size (except really tiny
windows).

128 isn't special and I could use a larger number (>130). However, since a
line is drawn diagonally across the full screen and sampled in its middle by
this test, certain width and height combinations fail.
Drawing a line doesn't seem too important to this test. Could a rect
be used instead to allow for larger variance in sizes to function? For
example, what if the default size was 150 for Windows, but something
small for Linux?

The default values
work but I am worried about the user overiding the default value (not sure
how that behaves). Other option is to make the test more robust to varying
window width and heights rather than fixing the window width and height to a
value that samples correctly.
