MatrixArray not supported

[stefnotch]

I tried writing a GPU skinning shader and wanted to pass an array of matrices to the shader.

However, the following error popped up when attempted to apply the current effect pass (someEffectPass.Apply())

System.NotSupportedException: 'Unsupported data type.'

After digging a bit into the source code, the cause of the error seems to be around here:

https://github.com/tlgkccampbell/ultraviolet/blob/823861bec534a6e7458436e06ec15baed0803668/Source/Ultraviolet.OpenGL/Shared/Graphics/OpenGLShaderUniform.cs#L135

It's missing the following lines of code:

case OpenGLEffectParameterDataType.MatrixArray:
    SetValue(source.GetMatrixArray());
    break;
