/*
 * ===  EASY DIFFICULTY WRITER API  ===
 *
 * Use a static helper function to create a VTF in one function call - VTF::create
 *
 * === MEDIUM DIFFICULTY WRITER API ===
 *
 * Constructing a VTF instance from existing VTF data will let you modify that data.
 *
 * This class has methods that should be called in a particular order
 * when creating a VTF from scratch, or your output VTF may look incorrect:
 *
 * 0. Construct an empty VTF instance
 * 1. Set the version (7.4 is the default)                 - VTF::setVersion
 * 2. Set FLAG_SRGB (optional, read for image resizing)    - VTF::setFlags
 * 3. Set the image resize methods (optional)              - VTF::setImageResizeMethods
 * 4. Set the base image (mip 0, frame 0, face 0, slice 0) - VTF::setImage
 * 5. Compute mips (optional)                              - VTF::computeMips
 * 6. Set the output format (optional)                     - VTF::setFormat
 *
 * After these methods are called, the other writer methods in the class should work as expected.
