Text rendering performance

[michel-pi]

I originally switched to creating a new TextLayout every time in the text rendering methods because their was a little bug (either in mine or SharpDX code) which let the renderer not draw or crash when using the DrawText method instead of the DrawTextLayout method.

I think this is no more an issue and can be changed if this provides better performance for text rendering.

Disclaimer: I assume that Direct2D just creates a TextLayout for you if you use the simpler methods.
