Ralized that the last line (vivante) of the above table is wrong for offscreen
results with TS enabled. Correcting it:

glmark2-es2-wayland  --off-screen -b shading:duration=5.0 -b refract -b build -b texture -b shadow -b bump -s 640x480 2>&1

|                      |                  glmark2 tests                              |
| sw ver               |shading|build|texture   |refract|shadow|bump |
|----------------------|-------|-----|----------|-------|------|-----|
| etnaviv (no TS)      | 348   | 541 | 466      | 24    | 81   | 498 |
| etnaviv              | 434   | 901 | 832      | 19    | 106  | 871 |
| vivante              | 402   | 624 | 520      | 26    | 177  | 557 |

With TS enabled, etnaviv offscreen scores seems to be overall better
than galcore.

Thanks!
