Fix behaviour when TrueColor / 24 bit depth is not available (#114)
* Fix regression introduced in c7ca547 which made nsxiv not start in non-TrueColor X server. * Introduce a new fix for embedding into tabbed-alpha. * Fixes a visual glitch from original sxiv when drawing transparent images in 8 bit depth. In 8 bit PseudoColor, `.pixel` is just an index into the 256 defined colors and thus trying to extract rgb bits from it would result in visual glitch. The values `.color.red` on the other hand and so on are always integers between 0 and 0xFFFF representing the color as expected. * Use XColor for win_bg/fg and mrk_fg Co-authored-by: NRK <nrk@disroot.org>
