Coding style issues in new rendering code

[dmorissette]

On a quick code review, I noticed some coding style issues in some of the new rendering code: at least maprendering.c, mapcairo.c and mapgeomutil.cpp are affected by one of more of those issues. It would be ideal to fix them ASAP before the 6.0 release so that eventual patches will be easier to port in the future between 6.0 and 6.x releases.

1- The standard MapServer header is missing in some of them.

2- The files use a mix of TABs and spaces for indent. The convention in MapServer source is that all tabs should be converted to the right amount of spaces so that indent is right in any editor, no matter what the tab size setting is in the editor. (Most editors have a setting to automatically convert tabs to spaces to help avoiding this problem in the future)

Note that emacs has macros to facilitate the fix of those issues, so most of the work after applying them should be reviewing the results for correctness. If you are not setup to do this easily then please let me know and I'll try to do it before next beta.

I'll take care of this since Thomas is away

Fixed in r11504.

Thomas: you may want to review the "Purpose" line in the header of each file and put something better than what I did.
