Scale form elements consistently
The ratios between the sizes of form elements, including text, is now fixed, aside from variations caused by rounding. This makes form layout almost fully predictable, and particularly independent of player's screen size. The proportions of non-text elements are the traditional proportions. For compatibility, the way in which element positions and sizes are specified remains unchanged, in all its baroqueness, with one exception. The exception is that the position of a label[] element is now defined in terms of the vertically center of the first line of the label, rather than the bottom of the first line of the label. This change allows a label to be precisely aligned with button text or an edit box, which are positioned in a centering manner. Label positioning remains consistent with the previous system, just more precisely defined. Make multi-line label[] elements work properly. Previously the code set a bounding rectangle assuming that there would be only a single line, and as a result a multi-line label would be cut somewhere in the middle of the second line. Now multi-line labels not only work, but have guaranteed line spacing relative to inventory slots, to aid alignment. Incidentally fix tabheader[] elements which were being constrained to the wrong width. Given an unusually large form, in variable-size mode, the form rendering system now chooses a scale that will fit the entire form on the screen, if that doesn't make elements too small. Fixed-size forms, including the main menu, are have their sizes fixed in inch terms. The fixed size for fixed-size forms and the preferred and minimum sizes for variable-size forms all scale according to the gui_scaling parameter.
