 /**
  * Returns a smoothly scaled image using getScaledInstance. This method has interesting behaviour.
  * The scaled image retains its type (indexed/rgb and bitmask/translucent), and the algorithm
  * tries to scale smoothly within these constraints. For indexed, interpolated pixels are rounded
  * to the existing indexed colours. For bitmask, the behaviour depends on the platform. On
  * WinXP/J1.2 I found that the colour _behind_ each transparent pixel is used to interpolate
  * between nontransparent and transparent pixels. On BSD/J1.4 I found that the colours of
  * transparent pixels are never used, and only the nontransparent pixels are used when
  * interpolating a region with mixed transparent/nontransparent pixels.
