[SDL] 1.2.8 -> 1.2.11 Upgrade

[hinko.kocevar at cetrtapot.si]

Hello,

I've upgraded SDL version from 1.2.8 to 1.2.11 and I'm noticing that 
colors are not the same. SDL is used on an embedded device with 8bpp, 
320x240 sized LCD.
My first investigations were around blitting code of the surface and I 
found out that several changes were made in that section 
(src/video/SDL_blit* files).

I guess that grey 'bars' appear 'cause of the low bpp for my embedded 
screen, no matter at least colors are right in the 1.2.8 version. The 
fact the testalpha forces the display to work at 16bpp instead os 8bpp 
doesn't seem to have any problems running on older version of SDL 1.2.8, 
if that would be the case for the 1.2.11...

When running testalpha on 1.2.8 version, grey bars are nicely stacked 
from black to white, with pale orange rectangle on the middle - which 
seems fine. But on 1.2.11 grey bars are not grey - just first bar is 
black and last is white, the ones in between are pink, yellow, green 
,white?. Plus the rectangle in the middle is pale green! Sprite is 
always yellow on 1.2.8, but is changing to some weird colors on 1.2.11.

I can confirm that running testalpha 1.2.11 version on the host works 
fine (smooth and at 32-bpp).

Cursor is nice in the both screens- probably 'cause it is only BW.

Can anyone give me some pointers what might be wrong?

best regards,
hinko
