Support grid layouts for bars

[trevorchipley]

For a while, there's been an ask for horizontal bar layouts (#82). This implements a more generalized version of that which should be able to handle any grid layout like 1x10, 10x1, 5x5, 3x8, and so on.

Summary of changes:

• Add configuration settings needed for grid layouts, keeping default settings as the current 1-column layout
  • Add settings related to columns (e.g. bar width)
  • Rounding options for all cardinal, inter-cardinal, and middle bars
    • Since some settings don't apply to 1xN or Nx1 layouts, only relevant settings are shown for those configurations
  • Update naming of some settings that were named based on the single-column layout
• Calculate bar layout up-front (CalculateLayout) and use the calculated layout to place the bars
  • Instead of the iterative approach DrawBars used to take, this does some math up front to determine the column and row counts based on the user's configuration and the number of combatants
  • Hopefully this reasonably easy to follow, if it needs clarification, let me know
• Update other elements of the drawing code to work well with grid layouts
  • Split rounding determination out of DrawBars, since grid layouts make it more complicated to decide what rounding to use
  • Scrolling scrolls one row at a time instead of one combatant
  • Column headers are drawn at the top of every column

The diff of all of this taken together is confusing, so I've tried to make the commit history clear.

Something horizoverlay-like, since the feature request mentions it:

Can you help me understand a use case for this? Sorry if this is offensive but the screenshots look bad. The whole point of a histogram style chart is for visual representation of relative values, and that utility is completely undermined by arranging the bars horizontally like this.

Horizontal layouts have been an open feature request for a while, and uses for it are around personal preference or fitting better into a UI (for example, a wide, relatively short window like the last screenshot could fit neatly under a player's hotbars, where a tall window likely wouldn't).

The broader grid layout is admittedly more niche, the only case I thought of is for seeing all players at once without an excessive vertical footprint in alliance raids or something like Baldesion Arsenal or CLL/Dalriada.

No offense taken. I agree that the horizontal growth of bars with the horizontal layout loses some visual clarity. In practice while using this the last few weeks, I've found it to be minor, though your mileage may vary. It didn't occur to me before your comment, but (an option for) vertical growth for the bar fill would help with this, right?
