(svn r11802) -Fix [FS#716]: do not crash trains when leaving depot to a very long track
-Codechange: use dedicated pathfinder for signal updating, resulting in better performance and possible future improvements

(svn r11490) -Codechange: Split the math functions to their own header
-Codechange: Replace the rest of the math macros with functions

(svn r11488) -Codechange: Spilt the random functions out to seperate file
-Codechange: Make the mersenne twister more readable
-Codechange: Unify the seeding process of random

(svn r11399) -Feature(ette): transparency settings can now be saved and thus remembered.
-Codechange: Wrap all transparency settings in accessors, hiding the implementation
-Change: Clicking "transparent building" menu will toggle Houses And Trees only. The other options can be used in the transparency gui.
Initial patch by Smatz (FS#1349), with some rework by BigBB and your humble servant.

(svn r11078) -Add: added 32bpp-optimized, which is almost twice as fast as 32bpp-simple (based on the work of frosch)
-Add: let 32bpp-anim use 32bpp-optimizeds, so he profits from the speed-up too

(svn r10190) -Codechange: merged renderer and blitter to one single class API: blitter
-Codechange: introduced a hierachy of blitters to avoid a lot of code duplication
Note: this allows much easier adding other types of video-drivers, like OpenGL

(svn r10182) -Codechange: rewrite most part of the file loading/searching to be more flexible.
-Codechange: add support for personal directories on Windows.
-Fix [FS#153, FS#193, FS#502, FS#816, FS#854]: fix issues related to fixed names, fixed places of files/directories and application bundles.

(svn r10179) -Fix: spritecache wasn't in source.list, thus wasn't in the MSVC project files.
-Fix: Pig Latin wasn't in the MSVC project files.

(svn r10143) -Add: store the filename of the grfs opened and allow easy access to the name
-Codechange: store the SpriteID in the spritecache too
-Add: add a PNG loader for graphical files
-Documentation: added a document to explain the PNG format

(svn r10132) -Codechange: split out the last direct video-buffer read access to the blitter-layer
-Add: added a new renderer and blitter to make room for some optimized bpp
-Fix: fill the alpha channel in the grf-spriteloader

(svn r10127) -Add: Addition of basic structure for industry tiles callbacks (unfinished).
-Codechange: ResolverObject receives member gfx, making it compatible for both industries and industry tiles
-Codechange: NewIndustryResolver now has his randombits and triggers (even if not implemented)

(svn r10121) -Codechange: split renderer from rest of code; no longer any code directly accesses the video-buffer
-Add: added NULL blitter and renderer, which are always used for -vnull
-Add: dedicated driver doesn't blit nor render by default. Can be overruled by user. (-D -b 8bpp-optimized)
-Remove: removed CTRL+D from win32, which is incompatible with above
-Add: extended screenshot support for PNG and BMP
-Codechange: remove all hardcoded 8bpp references and replace them with more dynamic ones
-Codechange: minor stuff in blitters

(svn r10092) -Codechange: code-seperated the spriteloader and blitter from the rest of the code
-Add: make it possible to pick your own blitter (-b <blitter>, -h for overview)
-Add: added a new optimized 8bpp blitter (default, caches sprites of all zoom-levels)
-Add: added a debug 8bpp blitter and a very slow normal 8bpp blitter

(svn r9850) -Codechange: Introduction of the Override/Substitute manager. Currently only used for newhouses.
Basically, it is more a gathering of IDs from grf files and ingame data.

(svn r9844) -Codechange: replace zoomlevel with an enum
-Codechange: use predefined enums for viewport zoomlevels

(svn r9315) -Merge: The newhouses branch. With this merge comes almost complete support for
the newhouses grf specs, so all newhouses grfs will be playable in the game.

Many thanks to everyone who contributed code and ideas, and all the testers
who found things we missed.

(svn r9082) -Codechange: [win32] Update VS2003 and VS2005 project files to use the same outpath, and build in UNICODE mode. When making a release it is probably better to make two binaries, one without UNICODE, the other with, guaranteeing full Win9x compatibility (UNICODE with MSLU also works, without it's even better).
-Remove: [os/2] Relic project file remains from watcom

(svn r8969) -Codechange: rework of the player face bits.
- introduce a new format (with backward compatability) that is more clear and needs a much simpler face drawer
- replace tons of ifs/switches/magic numbers by table lookups

(svn r8832) -Change: rewrite the solution file generator a little so it makes project files that look more like the ones generated by respectively MSVC2003 and MSVC2005.
For some reason the internal formatting of the XML between MSVC2003 and MSVC2005 differs, so adding a file in MSVC2005 would result in basically adding the entire openttd_vs80.vcproj to the diff.

(svn r8414) -Codechange: Use own AutoPtrT instead of std::auto_ptr.
-Simplifies assignment from raw pointers
-Should be harder to crash the program by incorrect assignment into it.
-Should help with MorphOS compilation errors

(svn r8371) -Codechange: [autoreplace GUI] moved the autoreplace GUI to a file of it's own
Note: it's the same as r8363, only this time the svn history of autoreplace should be preserved

(svn r7759) -Merge: makefile rewrite. This merge features:
- A proper ./configure, so everything needs to be configured only once, not for every make.
- Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies.
- A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC.
- Proper support for OSX universal binaries.
- Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files.
- Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files.

Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy.
