Wrong image depth displayed?

[fire-eggs]

The image from issue #105 is a 256 color image, yet YAIV title bar displays it to be a 4-byte depth image.

Using Xnview to resize said image and making sure the result resized image was also 256 color / 1-byte depth, YAIV title bar displays that image (see attached) to be a 3-byte depth image.

I've checked this issue too.
That very long image (20000 pixels ? wow ...) used color format to PAL(pallet-indexed) 8 bits.
I think this is automatically converted pallet index colors to RGB in Fl_RGB_Image.

My thanks for the diagnosis! Apparently I've not run into any pallette-based PNGs before ...
