Image class for encapsulating the storage texture image data

Image()

virtual Object* clone() const

virtual bool isSameKindAs(Object* obj)

virtual const char* className() const

const char* getFileName()

void setFileName(const char* fileName)

void setImage(int s, int t, int r, int internalFormat, unsigned int pixelFormat, unsigned int dataType, unsigned char *data, int packing=-1)

set the image data and format. note, when no packing value is negative (the default is -1) this method assumes a _packing width of 1 if the width is not a multiple of 4, otherwise automatically sets to _packing to 4. If a postive value of packing is supplied than _packing is simply set to that value.
