The spec states that GL_INVALID_OPERATION is generated when a shader or
program function is called on the wrong object type. GL_INVALID_VALUE is
generated when there's no shader nor program object by that name.

I looked into the texture size issue and I removed the " + Int(1)"
used on the LOD and replaced it with "baseLevel", which I think makes
more sense. Without the "+1", some tests using baseLevel==1 fail, but
all tests pass when I use "+baseLevel". I'm not 100% sure why the
"+1" wasn't making tests that were using baseLevel==0 fail.

Note that, for now, the new Sampler::State "baseLevel" member will
always be 0, as the code to set it hasn't landed yet and will be in
another cl.

By default vertex shader outputs/fragment shader inputs are
smoothly interpolated. The 'flat' keyword can be used to change
the interpolation to "flat", which basically means that no
interpolation is performed. "flat" is the only interpolation
qualifier accepted for integer types.

This change fixes all shaders/precision dEQP tests as well as a
few fragment output integer format types related tests.
