(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)
