(svn r7622) -Codechange: Convert some more windows to ShowQuery. This includes the depot
sell-all popup, quit/abandon game. The language files committed in r7619 go with this.

(svn r7410) -Codechange/Fix: Remove useless and unfollowable programmatic-resize, and implement it
in a sane way. Correctly specify resize flags for windows and only manually change the
widgets that the resize system cannot handle (eg centering). This changes r6562, and
probably some other commits

(svn r7403) -Codechange (r7386, r7385): Use available functions to find a window instead of doing
some cruft yourself (and wrongly typing non-const as const).

(svn r7386) -Codechange r7385: moved deletion of the vehicle highlight from DeleteVehicle to the sell commands as they are not called as often
Also added a return to the window loop prevent looking at the rest of the windows once the right depot window is found

(svn r7385) -Fix: FS#418 Deleting Train in depot with autoreplace failes
This turned out to be due to continue to drag the old vehicle, that autoreplace sold
This could also be triggered if more than one player used the same company
Now deleting a vehicle will remove all depot highlights of that vehicle

(svn r7206) -Codechange: Remove (some of) the magic needed for windows that could be invalid after
a call to DeleteWindow() somewhere else. Also do some cleanup with AllowWindowDescFront()

(svn r6961) -Codechange: Remove relic from r212 WWT_NODISTXTBTN which was originally used to not
to allow clicking if a button was disabled. This has been superseded in r212 with
general code that doesn't allow any click events for disabled buttons.

(svn r6925) -Codechange: Be more strict with widget distinctions. WWT_PANEL is only plain panel,
WWT_IMGBTN must contain an image for drawing. Renamed WWT_PANEL_2 to WWT_IMGBTN_2
because that is what it is. Added WWT_PUSHBTN that is either just a pushable button,
or a textbutton, which text's drawn dynamically independent of widget.

(svn r6922) -Feature: Add proper cloning sprites and cursors, different for each vehicle. Big thanks
to MB for the initial design and skidd13 for the iconified version(s).
-Codechange: Change the autorenew sprites from recycle to upgrade (skidd13)
-Codechange: Change the shared orders icon (MeusH)
-Add missing table/files.h file to VS project file.

(svn r6722) -Codechange: [aircraft build window] moved aircraft build window to a file of it's own
Also made some changes to it so it should be easier to unify all the build vehicle windows

(svn r6718) -Codechange: added function to get the line height for a vehicle type
-Fix r6513: [depot window] fixed incorrect line height for large ships
-Fix r6513: [depot window] fixed incorrect resizing of the sell button

(svn r6677) -Codechange r6651: [depot window] disabled the check for the correct cache in the depot window
Nobody had problems so far, so we can assume that InvalidateWindowData() is used everywhere where it's needed
The check is just disabled, not deleted so it's quick to reenable if we change some code and wants to check this again

(svn r6652) -Feature: [depot window] depot lists are now sorted, so vehicle 1 is always first and so on
This should not be a big slowdown as it's only called each time the list is generated and will normally be much faster than the list generation itself (only a small % of the total number of vehicles is in the depot)

(svn r6651) -Coding feature: added the windowevent WE_INVALIDATE_DATA
This gives the ability to invalidate some window data and recalculate as needed instead of doing it for each WE_PAINT

This event is called right away when using InvalidateWindowData(), so it may be a good idea to set a bool or similar in the window
or similar and then act on that bool in WE_PAINT instead of doing a lot of stuff in WE_INVALIDATE_DATA as it might be called more than once before WE_PAINT is called

InvalidateWindowData() will not automatically repaint the window, so if you want to repaint it as well, you need to mark it dirty as well.

Made the depot windows use WE_INVALIDATE_DATA to set when to generate the engine and wagon lists instead of at each redraw
It makes no sense to regenerate the list when say using the scrollbar if we know that no vehicle have entered or left the list

NOTE: currently there is a piece of code to generate the list when it's not needed and compare it to the stored list and assert if they mismatch
This check is somewhat slow and kills the whole idea of WE_INVALIDATE_DATA, so it's a short lived one to verify that InvalidateWindowData() is used everywhere where it's needed

(svn r6631) -Codechange: Use accessors for click_state.
Another step toward merging XTDwidget.
The only two files not converted (window.h and widget.c) will be done at the very last commit)

(svn r6619) -Codechange: Use accessors for disabled_state.
Another step toward merging XTDwidget.
The only two files not converted (window.h and widget.c) will be done at the very last commit)

(svn r6612) -Codechange: Use accessors for hidden_state.
Another step toward merging XTDwidget.
The only two files not converted (window.h and widget.c) will be done at the very last commit)

(svn r6593) -Fix: [depot window] added sprites to the buttons, that lacked one
Also changed the sprites on some of the other buttons to make the buttons consistent
Credits for this:
Drawing: skidd13 (first sprite copied/heavily inspired by Bot_40)

Sorry if I forgot to mention somebody

(svn r6591) -Codechange: changed strings that used the word "depot" into one for each vehicle type
This is a request from translators as depot is not valid for all vehicle types in all translations
This will cause a lot of warnings when generating the lang files. MiHaMiX will fix them in a moment (hopefully)

(svn r6586) -Feature: [depot window] added a vehicle list window with all vehicles having a certain depot in their orders
It got one known issue though. The top bar got a plural issue so expect to see stuff like "1 trains" until we figure out why it behaves this way
Added the button to the depot windows. Made the autoreplace button bigger while I was moving some widgets anyway
Made road vehicle depot windows start with one more row to make room for the buttons

(svn r6567) -Fix r6542: [depot window] solved an issue where the confimation window sometimes failed to close (spotted by MacLir)
Also changed the colours of the confimation window. Hopefully it looks better now even though I'm still not really happy with it

(svn r6562) -Codechange: merged the vehicle list window widget arrays
It made no sense to maintain 8 nearly identically arrays when a single one can do the job
Also made the two buttons always use half of the bottom width each, even when resizing

(svn r6552) -Feature: [depot window] added a "autoreplace all vehicles in depot" button
Like the "sell all" button, this one lacks a sprite as well. We will hopefully get one shortly

(svn r6542) -Feature: [depot window] added a "sell all vehicles in depot" button
It's right below the sell button (sell whole chain button for trains)
It's still missing a sprite. That one will be added as soon as anybody draws something we can use
To make room for this button, all depots except train depots now opens with an additional row and can't be resized shorter than that

(svn r6529) -Fix r6513: [depot window] added missing switch in CcCloneVehicle()
The result of this missing switch was asserts in some cloning conditions (not all) (spotted by KUDr)

(svn r6527) -Codechange: [depot window] added asserts to ensure that widget names, widget array and array of resize info stays the same length
Really bad stuff will happen if one of them contains a different number of widgets ;)
This is meant as a protection against incorrect additions of code rather than verifying that the current code works

(svn r6526) -Codechange: [depot window] the train only widgets are now resized depending on the size of other widgets
This will ensure that say the horizontal scrollbar is as wide as the matrix even if only the matrix is altered in size
This is meant to make it easier to add more widgets without coding a lot of vehicle type specific stuff (you should still check all windows though)

(svn r6522) -Feature: [depot window] the buttons are now "scaled" resized
This means that "Build vehicle", "Clone vehicle" and "Location" will always fill the space from the left window border to the resize button and they are equal in size
The sell button will also use all the space between the start/stop buttons and the resize button and for trains, the sell button is split into two buttons in equal sizes
This will prevent the issue where a small window is resized into a large one and the buttons remains pretty small
-Codechange: [depot window] The enum with widget names is now changed into automatic numbering so all lines will not have to be changed each time a new widget is added

(svn r6516) -Fix r6513: killed warnings about two variables being used uninitialized
This is not even correct since it's set in if (a) and later used in another if (a), but GCC didn't detect that

(svn r6513) -Codechange: unified the code to draw depot windows
This change is intended to make it easier to make depot behaviour consistent
and faster to code when adding more features in the future
The user interface should hopefully not be affected by this
