(svn r24991) -Doc: Clarify comments regarding settings macros.
(svn r24992) -Codechange: [SDL] Make CreateMainSurface and PollEvent private methods instead of static functions.
(svn r24993) -Fix: [SDL] Improve 8bpp hardware palette support. Instead of always requesting SDL_HWPALETTE, it is now only done for 8bp blitters in fullscreen mode.
  - This fixes 32bpp blitters on 8bpp X11, which would only render garbage with SDL_HWPALETTE.
  - This prevents the colors of other applications from being messed up when running a 8bpp blitter on a 8bpp system.
  - When running a 8bpp blitter on an 8bpp system without SDL_HWPALETTE (e.g., in windowed mode), this uses a new shadow surface with color approximation.
  - The use of a hardware palette can be forced on and off using -v sdl:hw_palette=1 or -v sdl:hw_palette=0
(svn r24994) -Codechange: Replace access to service_interval with accessors (peter1138)

(svn r24996) -Change: Apply default service interval changes to vehicles without custom interval (peter1138)
(svn r24997) -Change: Use dropdown list to select between Default/Days/Percentage (peter1138)
(svn r24998) -Fix [FS#5137]: Set vehicle's service interval is percent flag appropriately on creation (peter1138)

(svn r25001) -Change: heading for 1.4 now
(svn r25002) -Doc: [SDL] Fix typo in comment.
(svn r25003) -Fix (r24993): [SDL] Keep a flag to remember if a hardware palette was requested.
  - Previously, the code would query the SDL_HWPALETTE flag, which doesn't always match the requested value.
  - This would cause SDL to be restarted on every window resize event, effectively breaking resizing.
