// 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.
