IMPORTANT: Some renamings. Will need to be applied carefully to the carbon repository, in the following order: -- pixel_to_char_size -> pixel_to_frame_unit_size -- char_to_pixel_size -> frame_unit_to_pixel_size -- pixel_to_real_char_size -> pixel_to_char_size -- char_to_real_pixel_size -> char_to_pixel_size -- Reverse second and third arguments of change_frame_size() and change_frame_size_1() to try to make functions consistent in putting width before height. -- Eliminate old round_size_to_char, because it didn't really do anything differently from round_size_to_real_char() -- round_size_to_real_char -> round_size_to_char; any places that called the old round_size_to_char should just call the new one. 2. IMPORTANT FOR CARBON: The set_frame_size() method is now passed sizes in "frame units", like all other frame-sizing functions, rather than some hacked-up combination of char-cell units and total pixel size. This only affects window systems that use "pixelated geometry", and I'm not sure if Carbon is one of them. MS Windows is pixelated, X and GTK are not. For pixelated-geometry systems, the size in set_frame_size() is in displayable pixels rather than total pixels and needs to be converted appropriately; take a look at the changes made to mswindows_set_frame_size() method if necessary. 3. Add a big long comment in frame.c describing how frame geometry works. 4. Remove MS Windows-specific character height and width fields, duplicative and unused. 5. frame-displayable-pixel-* and set-frame-displayable-pixel-* didn't use to work on MS Windows, but they do now. 6. In general, clean up the handling of "pixelated geometry" so that fewer functions have to worry about this. This is really an abomination that should be removed entirely but that will have to happen later. Fix some buggy code in frame_conversion_internal() that happened to "work" because it was countered by oppositely buggy code in change_frame_size(). 7. Clean up some frame-size code in toolbar.c and use functions already provided in frame.c instead of rolling its own. 8. Fix check_frame_size() in window.c, which formerly didn't take pixelated geometry into account.

/* Building under cygwin
 *
 * The approach I have taken with this port is to use primarily the
 * UNIX code base adding stuff that is MS-Windows specific. This works
 * quite well, and is in keeping with my perception of the cygwin
 * philosophy.  Note that if you make changes to this file you do NOT
 * want to define WIN32_NATIVE (formerly "WINDOWSNT"), I repeat - do
 * not define this, it will break everything horribly. What does get
 * defined is HAVE_MS_WINDOWS, but this is done by configure and only
 * applies to the window system.
 *
 * When building make sure your HOME path is unix style - i.e. without
 * a drive letter.
 *
 * once you have done this, configure and make.
 *
 * windows '95 - I haven't tested this under '95, it will probably
 * build but I konw there are some limitations with cygwin under 95 so
 * YMMV. I build with NT4 SP3.
