Widescreen improvements

[Ghabry]

Like everything else the map is now centered when fake resolution is active. Should improve the UX because it gets rid of some glitches :).

First two commits are not changing any behaviour.

3rd commit allows to change the resolution while in the title scene. Until now this didn't work without: Start game, press F12.

4th and 5th commit: 4th results in the screenshot in the middle and 5th results in the screenshot at the bottom. (top is before) Cropping the panorama makes sense here because technically it is drawn outside of the size of the map, nothing should be drawn their.

Another example using Fake Res for a custom resolution. That map is again 20x15. Cropping works.

There is one annoyance left: On looping maps that are smaller than the screen the camera is positioned incorrectly. Unfortunately cannot figure out how to solve this. The scrolling code is complicated ^^'

• The transitions Zoom In and Zoom Out are not properly centered on the player on small maps (shown here with Deep Dreams, first screen is the original resolution and second screen is widescreen)
  
  
• The battle animations are not properly centered on the player/target on small maps (shown here with Yume Nikki, first screen is the original resolution and second screen is widescreen)
  
  
• The artifacts of some transitions can be shown outside of the size of the map, not sure if it's intended (Need more testing I guess)

Outside of this, the only thing that may need to be changed is how the battle UI is rendered I guess since it's a bit weird, though I'm not sure how it could be done correctly.

Looking good besides the mentioned by Mimigris, however there are some cases for new games where some picture behaviour is desired with the legacy way, e.g. for custom HUD positioned on screen corners. Maybe getting this under some configurable feature later is worth.

ready now. Fixed centering for battle animations and zoom on actor.

2k battle Ui is not scrolling anymore in widescreen mode. For 2k3 I will postbone this for later as this requires implementing it 3 times for all these modes...
