…xture

The first version of this fix only null-guarded the uvTransform
uniform assignment. That left EffectPass out of sync: clearing
texture does not fire a change event unless setVertexShader() or
setChanged() runs, so the compound material kept compiling with
the UV_TRANSFORM code path and the now-null uvTransform uniform.
On the next render, three.js's WebGLUniforms would read .elements
off that null value and crash, just not at the assignment site.

Mirror the non-null branch: delete the UV_TRANSFORM define and
call setVertexShader(null) when the texture is cleared, so
EffectPass recompiles without the stale uniform reference. Added a
test that builds a real EffectPass around the effect and checks the
compiled vertex shader no longer references UvTransform after the
texture is cleared.
