070558c4c4 GRAPHICS: do not reset the extra parameters of IFFDecoder on destroy(). 
The two properties that control pixel packing and the size of the
surface need to be preserved for loadStream() to work correctly.
They are now under complete responsibility of the client.

92c1ff31d6 GRAPHICS: do not clear the internal state of IFFDecoder on loadStream(). 
This decoder needs to keep track of client parameters that control
how the pixels are going to be packaged, so the responsibility for
clearing the state has been moved on the client (using the destroy()
method on ImageDecoder).

As no client uses the IFFDecoder for more than one image at a time,
this change does not require updates to the engines. The only effect
is on Parallaction (BRA-Amiga), which can now control the way pixels
are packaged in mask and path bitmaps.

4809294b43 GRAPHICS: Make JPEGDecoder request RGB output from libjpeg by default. 
This fixes loading of JPEG files which contain RGB color space instead of YUV.
It is a pretty odd extension of JPEG files by Adobe which is indicated by this:
http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/JPEG.html#Adobe

To still support Groovie's need for YUV data I added some possibility to
request direct YUV output.
