Vimana-X HUD
============
By Gnievmir and phkb

Overview
========
Gnievmir's original Vimana HUD has earned a lot of praise for the stylish layout of the graphical dials and other UI bells and whistles. However, I always struggled to choose it for a number of reasons:
- It seemed to be designed with a single font in mind. Using a different font leads to a lot of text overrunning the graphical bounds of the UI, or not aligning correctly.
- It also seemed to be designed with a very specific group of OXP's in mind. If those OXP's are missing then parts of the UI were effectively useless.
- When viewing any of the F5-F8 pages during flight, or when going to the F2 screen after pausing, the HUD would overlap parts of the screen, making some things difficult to read.
- The Ship info and Target info panels are useful, but only a limited number of ships would be shown as an image.
- The "Mode" information for certain primable OXP equipment items was limited in what it would show.
- The jump distance indicator on the fuel gauge would only show after the Travel Module was purchased.
- An "uber" laser was included in the original Vimana HUD, as well as a targeting equipment item. Both were better suited to separate OXP's.

So, I embarked on a tweaking session, which turned into a design/layout session, which turned into a much bigger update than I was expecting. However, I feel the result is worth it. Here's a complete breakdown of everything I did:

1. I divided the UI up into two, with only the scanner and core dials and gauges showing whenever a non-viewscreen view is selected.
2. I repositioned some components to allow for some greater flexibility with other items. I repositioned the injectors icon, the fuel scoop icon, and the fuel warning icon to be inside the speed, cargo and fuel gauges respectively, which allowed me to move the shield capacitors icon, shield cycler icon and EEU icons to the left side of the UI. This then allowed enough room to add an additional gauge which is used for aft armour (at present, this is only used by Ship Configuration, but if other OXP's deploy aft shields it can be configured to use that as well).
3. I darkened the background of the UI substantially, making it less transparent, and therefore better able to cope with high-glare environments. But in case anyone was particularly attached to the "light" version, it can still be used as an option (selectable from an F4 interface screen).
4. I reworked much of the text alignment code to ensure all the displays would work well with every font available. So columns will line up, text will be centred where required, and text items will not go beyond the bounds of the UI (mostly!).
5. I looked at how it works with other OXP's and tried to expand the possibilities and remove the locked-in feeling with some of the UI elements. In particular, the Anti-missile system and the Self-Repair system, which had their own lines on the UI. I switched this for a customisable system to allow for future OXP integrations, and added a couple of extra options to select from. There is now a F4 interface page, "Vimana-X HUD Settings" where the different options can be selected.
6. I expanded the "MODE" display for primable equipment, finding as many OXP's as I could that make use of this feature and adding the appropriate text.
7. I added alert icons inside each of the items that can cause alerts (altitude, cabin temp, energy, shields), and a missile warning icon in the combat HUD, to complement the larger warnings that appear at the top of the screen. If you find the top screen icons too intrusive, they can be turned off via the interfaces page, leaving just the smaller alert icons on the HUD. Also, I removed the text from the alert images, leaving them as images, and added text to the HUD, so that the warnings will appear in whatever font the player has chosen to use.
8. I added a bunch (600+!) of extra ship images from a variety of sources, so chances are a ship image will display in the left panel in the majority of cases. I also redid the existing images, because I couldn't reproduce the style of the original. What I've used is the wireframe version of all the ships, which carries a nice blueprint/schematic style to the ships. If I've left out your favourite ships, just let me know and I'll include them in a future release.
9. I changed the way the "scan" component works. In the original HUD, different parts of your ship would be highlighted individually, as if a "scan" was taking place. However, given the number of new ship images I was adding, it would be a mammoth task to divide each one up into four to keep that system. So I implemented a new "scan" that will work for whatever ship is displayed.
10. I changed the colour of the jump distance indicator in the fuel gauge, to make it stand out more. 
11. I changed the source of the targeted ship's weapon, taking it from Combat MFD's data, so that it matches what you see in that MFD, but also so that some information isn't revealed before the player has any right to know.
12. I added an icon for the naval energy unit, to make it distinct from the normal one.
13. To aid with startup timeout issues, I made the various timers start in sequence, and play a small sound when they turn on, to indicate the systems are starting up.
14. I added a 10-MFD version of the HUD, as well as reducing the size of the lower left and right MFD's on the 12-MFD version, to prevent them from overlapping the UI on a 16:9 display. If you use the 12-MFD HUD, and your screen dimensions cause the lower left and right MFD's to overlap the UI, and it doesn't make your eyes twitch, then everything is fine! But if you find small details like that really annoying, and you really need all the MFD's you can get, I'd recommend the 10-MFD version. I won't judge.
15. I turned on the non-linear scanner and ultra zoom options on the HUD. Plus added options to change these settings on the F4 interface page.
16. The Alt gauge will now reset when entering interstellar space.
17. Only equipment that is visible on the F5 page will be shown on any damaged equipment list.
18. Lots of small bug fixes, code tweaks and performance improvements.
19. I removed the targeting equipment item and the "uber" laser. It's now just a HUD. If you really want to keep those items, you should keep the original Vimana HUD OXP installed. There should be no conflicts between the HUDs.

If you have previously used the Vimana HUD, and purchased the Target, Travel and Ship modules for it, you will have those modules added automatically when you install this HUD.
