Patch for png_save(), QEMU v8.0

[Валентин]

Hello! 

 

Currently, png_save() in "console.c" uses "PIXMAN_a8r8g8b8" format when saving png. 

 

( https://gitlab.com/qemu-project/qemu/-/blob/7c18f2d663521f1b31b821a13358ce38075eaf7d/ui/console.c#L314 ) 

 

It should probably use "PIXMAN_a8b8g8r8" (red<>blue exchanged). 

Without it I'm getting PNGs with blue and red channels swapped (QEMU 8.0, qemu-system-x86_64, Arm64 host, libpng 1.6.39). 

 

Steps to reproduce: in QEMU 8.0 console execute "screendump /path/to/screenshot.png -f png". 

 

The patch is in attachment. 

With best regards, 

Valentine.
