+//
+// This is an "terminology reversing" implementation in the sense that
+// * "column" in Slang code maps to "row" in the generated WGSL code, and
+// * "row" in Slang code maps to "column" in the generated WGSL code.
+//
+// This means that matrices in Slang code end up getting translated to
+// matrices that actually represent the transpose of what the Slang matrix
+// represented.
+// Both API's adopt the standard matrix multiplication convention whereby the
+// column count of the matrix on the left hand side needs to match row count of
+// the matrix on the right hand side.
+// For these reasons, and due to the fact that (M_1 ... M_n)^T = M_n^T ... M_1^T,
+// the order of matrix (and vector-matrix products) products must also reversed
+// in the WGSL code.
+//
+// This may lead to confusion (which is why this note is referenced in several
+// places), but the benefit of doing this is that the generated WGSL code is
+// simpler to generate and should be faster to compile.
+// A "terminology preserving" implementation would have to generate lots of
+// 'transpose' calls, or else perform more complicated transformations that
+// end up duplicating expressions many times.
