File 0002-Skip-processing-unknown-uniforms.patch of Package libqt5-qtquick3d.35247

Subject: [PATCH] Skip processing unknown uniforms

While processing shader uniforms, it can face
vendor specific uniforms. Quick3D will skip
them because they are not interesting in
the pipeline.

And for GL_TEXTURE_2D_MULTISAMPLE, pnames which
are related with sampler states, are not allowed.
So, they will not be set.

Fixes: QTBUG-110039
