Given a text property and a string, get the bounding box [xmin, xmax] x [ymin, ymax]. Note that this is the bounding box of the area where actual pixels will be written, given a text/pen/baseline location of (0,0). For example, if the string starts with a 'space', or depending on the orientation, you can end up with a [-20, -10] x [5, 10] bbox (the math to get the real bbox is straightforward). Return 1 on success, 0 otherwise. You can use IsBoundingBoxValid() to test if the computed bbox is valid (it may not if GetBoundingBox() failed or if the string was empty).

Given a text property and a string, this function initializes the vtkImageData *data and renders it in a vtkImageData. textDims, if provided, will be overwritten by the pixel width and height of the rendered string. This is useful when ScaleToPowerOfTwo is true, and the image dimensions may not match the dimensions of the rendered text.

Should we produce images at powers of 2, makes rendering on old OpenGL hardware easier. Default is false.
