-  std140 problem with uniform buffers
+  std140
+    Right now, buildStruct packs an array, which is changed to a typedarray and fed to a GPUBuffer
+      That limits the type to whatever the typedarray is
+    Instead, we need to represent the type of each value, and write it as such
+      Create an array buffer
+      Create a Float32Array view into it, and an Int32Array view
+      Transcribe the values into these views
+      Return the array buffer
+
