Nigel Tao 4f42fa989e go.mobile/gl: use column major ordering.
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.
