+Warning: Do NOT regenerate the .qsb files without proper planning and understanding

+
+Among other things, we are also testing backwards compatibility for QShader
+deserialization.
+
+.qsb files with _v1 in the name were produced with an older qtshadertools
+and have a QSB_VERSION of 1.
+
+Files with _v2 are generated with a newer qsb, those have QSB_VERSION 2.
+The difference is the support for nativeResourceBindingMap() which is only
+present in v2.
+
+Files with _v3 come from an even newer qsb, and have QSB_VERSION 3. The
+difference to 2 is the use of CBOR instead of binary JSON for QShaderDescription.
