/**
|
|
* Stores the entirety of a LookAndFeel's data.
|
|
*
|
|
* The format allows for some compression compared with having fixed
|
|
* length arrays for each value type and some indication of whether
|
|
* a value is present. This is because not all values are present on
|
|
* a given platform, and because there is also substantial repetition
|
|
* of specific values.
|
|
*
|
|
* Each of ints, floats, colors, and fonts is an array that stores the
|
|
* unique values that occur in the LookAndFeel. intMap, floatMap,
|
|
* colorMap, and fontMap map from value IDs (LookAndFeel::IntID, etc.)
|
|
* to indexes into the value arrays. The map arrays are of fixed
|
|
* length, determined by the maximum ID value. If a value for a
|
|
* particular ID is not present, the entry in the map is set to -1.
|
|
*
|
|
* (Note that fontMap is different from the others since it maps from a
|
|
* LookAndFeel::FontID value minus 1, as 1 is the minimum value of that
|
|
* enum.)
