Draw a texture in the Scene.

The chosen texture is drawn in 3D space on a "screen" defined by the XY plane (ie, the plane where the Z coordinate is zero). The values of the texture rectangle are given in Scene units. The optional border values specify an inset from each edge within the rectangle in Scene units; the texture is drawn inside the inset rectangle and the edge pixels are repeated outwards. This is a useful quick way to create a large background region around the main texture when its edges are of a single colour.

This function can be useful for creating GUI backgrounds in conjunction with a camera pointing directly at the texture.
