// Helper method to initialize a bitmap image from KeyValues data..

// image data. The parent argument specifies which panel to use as parent,
// and the final argument is the bitmap image to initialize.
// The function returns true if it succeeded.
//
// NOTE: This function looks for the key values 'material' and 'color'
// and uses them to set up the material + modulation color of the image
