Also rename some files: types.go -> types_prod.go typesdebug.go -> types_debug.go (new file) types_common.go In discussing https://golang.org/cl/144480043/ crawshaw said: The third argument to glUniformMatrix* is "transpose." According to the linked documentation, which is usually better: "If transpose is GL_FALSE, each matrix is assumed to be supplied in column major order. If transpose is GL_TRUE, each matrix is assumed to be supplied in row major order." However, the documentation for OpenGL ES 2 doesn't bother even telling you, it just says that this parameter must always be set to GL_FALSE. So it's not supported on most Android devices. (Sadly the older documentation appears to have been discontinued.) So yes, GL seems to default to column-major, and the older GLES2 I'm targeting left the transpose argument in but doesn't support it. Hence I'm not exposing it through this API.
