These files are used by anaconda during the installation process. A
basic description/specification for them is as follows:
* anaconda_header.png: This is strip header at the top of
the screen during the install. 800x58.
* progress_first.png: First graphic displayed during package
installation. If there are no rnotes, this is displayed the entire
time. 500x325
* progress_first-lowres.png: Lowres version of progress_first.png. 350x225
* splash.png: Splash screen shown on the "Welcome to ..." screen.
400x420
* syslinux-splash.png: Splash screen used at the boot prompt with
syslinux/isolinux. This gets transformed into the syslinux specific
format. 640x300. This uses a 16 color palette (should be an indexed png).
You should ensure that 0 = #000000, 1 = #ffffff, 7 = #cdcfd5, 15 = #c90000.
Alternately, you can use 12 colors and have them be any that you want.
* syslinux-vesa-splash.jpg: Splash screen used at the boot prompt when
using the menu. It should be 640x480 RGB. Can just be a conversion
of the grub splash and work well.
