A small program to demonstrate the issue

It seems that a texture bound in the previous draw call is used by
textureSize() and textureQueryLevels() (instead of the currently bound
texture).

The attached program demonstrated the bug. When the program is built with
-DBROKEN, it incorrectly prints "width: 2.000000 height 2.000000 miplevels
2.000000" while the current texture is 512x256 with 4 miplevels.

OpenGL vendor string: nouveau

OpenGL core profile version string: 4.1 (Core Profile) Mesa 11.0.5
OpenGL core profile shading language version string: 4.10
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
