UniformMatrix4dv is Broken

[rileylyman]

At least for me, using gl::UniformMatrix4dv supplies the shader with a matrix filled with zeros, whereas gl::UniformMatrix4fv works as expected. I ran the exact same code to test both functions, the only difference was that I replaced the former with the latter, and I cast each element of my matrix buffer to an f32. Has anyone else had this happen to them, or would anyone like to test on their own box? If needed, I could possibly come up with an example to illustrate.
