// In determining the number of guidelines to display, it must be kept in mind that
// the spacings between the lines might be variable depending on the
// current time unit. For instance, if the timeline is measured in months, then the
// lines will not be equally spaced apart because a month is anywhere from 28 to 31 days.
// The solution is to produce lines one at a time while the total accumulated width is
// less than the viewport width.
//
// 1. First we first convert the current horizontal offset into a TimeSpan, and add
// that to the timeline's start time to get the time of the viewport's left edge. This
// time may be more precise than the timeline's current unit of measurement. For
// example, the viewport left time may be defined down to the second, but the timeline's
// unit is an hour. Therefore, we must round up to the nearest unit.
//
// 2. The difference between the rounded date and the precise date is the time between
// the start of the viewport and the initial line. Converting this TimeSpan into pixels
// will yield the x position of the initial line relative to the viewport's left edge.
// We can store this value along with the line number for use during the arranging process.
//
// 3. Now we can create a guideline, add it to the panel, and measure it.
//
// 4. Next we increment the rounded date by whatever is set as the timeline's unit.
//
// 5. Repeat steps 2 to 4 until the rounded date is equal to or exceeds the date of the
// viewport's right edge.
