Support for bitmap image formats

[Martin Schulze]

Hi,

is there a reason the render engine is limited to support only JPEG
and BMP?  The wxWidgets library seems to support more image formats,
such as commonly used TIFF, PNG, GIF, or less commonly used PNM, PCX,
XBM and XPM, just to name some.

I've just tested whether the engine can handle PNG, TIFF and GIF,
which worked fine.  I know that's not a proof, but only a
circumstantial evidence.

Attached is a patch that would add these formats.

Regards,

	Joey
