translate+scale -> scale+translate

This is a no-op refactor.

It's just always surprised me that the matrix_scale_translate
stage expects [tx ty sx sy], when scales precede the translates
in the names and in both normal row-major and column-major matrix
layouts.

This switches to [sx sy tx ty], scale then translate.
