texture-integer-glsl130: Expect 1 for alpha in R, RG, RGB cases.

Table 3.23 (on page 221) of the OpenGL 3.0 specification is:

+----------------------------------------+
| Texture Base    | Texture source color |
| Internal Format |    C_s          A_s  |
+-----------------+----------------------+
| ALPHA           | (0, 0, 0)    |   A   |
| LUMINANCE       | (L, L, L)    |   1   |
| LUMINANCE_ALPHA | (L, L, L)    |   A   |
| INTENSITY       | (I, I, I)    |   I   |
| RED             | (R, 0, 0)    |   1   |
| RG              | (R, G, 0)    |   1   |
| RGB             | (R, G, B)    |   1   |
| RGBA            | (R, G, B)    |   A   |
+-----------------+----------------------+

From this, we see when sampling from RED, RG, and RGB textures, alpha
is supposed to be one.

v2: Change commit message to quote the right part of the spec.

Revert "texture-integer-glsl130: Expect 1 for alpha in R, RG, RGB cases."

This reverts commit cf47699087f74a6fd94c59a74837fc6c3c6422a8.

While I still believe the test is wrong, apparently this change made it
worse; the test doesn't quite work like I thought.  More investigation
is needed.  In the meantime, restore the old behavior.
time-elapsed: Spend time in the FS rather than do a lot of draws.

The time-elapsed test needs to consume a lot of GPU time so that it
can validate GPU time queries against elapsed wall-clock time.
Previously we did this by painting the window thousands of times.
That sometimes caused false failures due to the CPU time consumed in
preparing the draw calls.

This patch changes the test so that it consumes time by using a slow
fragment shader rather than by painting the window over and over.
glslparsertest: Use integers for GL and GLSL versions

I haven't observed any failures with this yet.  Since we just did the
same thing with shader_runner, it seems like a good idea.
