Bad rgb_color value on archiving BView

[shinta]

I archived and flattened a BView whose view color is R=0x01, G=0x02, B=0x03, A=0x00. When I viewed the flattened file with ViewIt, view color as int32 is 0x00030201 (order is ABGR).

In contrast, I got int32 value 0x01020300 (order is RGBA) in ZETA. Maybe, BeOS R5 is same with ZETA.

Archived BView in Haiku.

I modified View.cpp as DigestCode2094.cpp and BView works well.

My concern is:

• Whether this code works well on PPC version of Haiku.
• Whether some function like swap_uint32() already exists.

Looks good, thanks!, I would just merge swap_uint32() and get_uint32_color() into a single function.

Fixed in hrev25031. On second thought, your swap_uint32() function was misleading, as we actually need to have the int32 in host endian before passing it to AddInt32() - as the BMessage takes care about endian already.

Thank you for modifying my code!
