Lots of code style fixes:
* type [*&]varname -> type[*&] varname
* else
if (...)
->
else if (...)
* Spaces around some ops.
* i++ -> ++i.
* switch-case style fixes.
* Indentation fixes.
* Removing some commented out code.
* include header sorting
* Changed multiple pointer var declarations to be one per line.
* Removed strange spaces in some places.
* Changed some include header guards to be consistent with the rest of
the codebase.
* Use UNUSED() instead of UNUSED2().
Some small code fixes:
* Using .find() instead of .count() == 0.
* !.empty() instead of .size() == 0.
* Range-based for loops.
* Making some member functions const by small changes.
* Adds GetScrollBarPos(idx) const for this.
* Using early returns/continues in some places.
* Uses size_t for some loops in CList and COList.
* Removes unused heading element (not attribute) from COList.
* Use ENSURE in one case where some custom code did something similar.
* Made some parameters const ptrs/refs.
* Change removal loop in GUItext.cpp to erase-unique.
* Made some static things const.
* Allow iterating over children of IGUIObject with range-based for
loops by
exposing begin() and end() (rename from ChildrenIt{Begin,End}()) and
use it.
Comments:
* Comment COList.
* Update a few comments.
* Remove useless or duplicated comments.
This was SVN commit r16931.
