* @help
* Adjust the parameters as you see fit.
* Most of them should be pretty self-explanatory, but there are a few new
* features added by this plugin.
*
* Subtitle
* Allows for an optional subtitle to be placed beneath your title.
* To use this, you must have "Draw Game Title" enabled.
* The subtitle may either copy the title's colours, or draw from its own pool.
*
* Hue min/max
* Allows for setting a minimum and maximum hue adjustment that will be applied
* at random to the title1/title2 image.
*
* Titles2 (Foreground)
* By default, MV draws titles1 and titles2 images on the background layer.
* This allows you to draw another image from titles2 on the foreground layer, in
* addition to the default background titles2 image.
*
* Title BGS
* Allows you to include an optional BGS to play alongside the title BGM.
*
* Pitch min/max
* Allows for setting a minimum and maximum pitch that will be applied at random
* to the BGM/BGS
* 
* Reroll Frequency
* This allows you to determine how often the images or BGM/BGS will be rerolled.
* Once only - Roll once, upon booting up the game.
* (restarting the game via F5 also counts as booting up the game)
* After game - Reroll after entering and exiting a playthrough
* (i.e. game over / game end / return to title)
* Always - Reroll every time the title screen is entered
* (i.e. after adjusting options from the title screen, or if you have custom
* scenes accessible from the title)
*
* TERMS OF USE
* - Free for commercial and non-commercial use, as long as I get a free copy
*   of the game.
* - Edits allowed for personal use.
* - Do not repost or claim as your own, even if edited.
* 
* VERSION HISTORY
* v1.0 - 2023/7/8 - Initial release.
