Small patch to clean up the boot splash logo for D6 cameras. The CHDK logo bitmap needs to be slightly higher on the splash screen to align with the text box using srsa_4c's new font scaling.
There might be a better way to do this - I just adjusted the hard coded offset in gui.c for D6 builds - i.e.: #ifdef THUMB_FW
int offset_y = ((camera_screen.height-LOGO_HEIGHT)>>1) - 66 ;
#else
int offset_y = ((camera_screen.height-LOGO_HEIGHT)>>1) - 42 ;
#endif
A better way to do this could be either logo scaling code or a new D6 logo.dat file.
