Allow texture creation to occur on any thread (rather than the dedicated render thread).
When set to true, textures can be created on a separate thread, rather than being restricted to the dedicated render thread.
This results in less hitches during asynchronous loading as it removes some work from the render thread.
When this is set to false, texture creation occurs on the render thread.
The setting defaults to be true if the platform supports creating textures on a separate thread.
If the platform doesn't support creating textures on a separate thread Texture.allowThreadedTextureCreation will always return false, even after setting to true.
