//////////////////////////////////////////////////////////////////////////////
// //
// pfJournalBook Class //
// A generic, high-level, abstract method of creating various Myst-like //
// books within the game with very little effort, while ensuring that they //
// all remain consistent in appearance and operability. //
// //
//////////////////////////////////////////////////////////////////////////////
// //
// Journal books are created via a journal book template. The template //
// takes the form of an extremely simplified version of HTML. The esHTML //
// has the following tags defined: //
// <p> - Start of a new paragraph. </p> isn't used. //
// <img> - Places an image in-line with the text. Options are: //
// align=left/right/center //
// src=<name of plMipmap> //
// link=<eventID> - Defines the image as clickable. When the user //
// clicks the image, it will generate an event //
// with the given event ID and send it to the //
// calling Python handler. //
// blend=none/alpha - Controls the blending method of drawing //
// the image //
// pos=<x>,<y> - Positions the image absolutely on the page //
// using the upper-left pixel given. Absolute- //
// placed images have no effect on text flow. //
// glow=<seconds[,min,[max]]> //
// - Defines a glow special effect, which amounts //
// to the image oscillating in opacity across //
// the time interval specified. Optionally, you //
// can also specify the min and max opacity, //
// from 0 to 1. //
// check=<onColor,offColor,default> //
// - Makes the image act as a checkbox, flipping //
// between on and off states (as defined by the //
// blending colors) on clicks. Default is either //
// 1 for on or 0 for off. Link notifys are sent //
// by checkboxes, with the event type //
// "kNotifyCheckUnchecked" negative if the //
// state is switching to off. Cannot be used //
// with "glow". //
// resize=yes/no - Defines whether the image will be resized //
// with the book or not, defaults to yes //
// opacity=0 to 1 - Defines the opacity of the image, 0 is //
// completely transparent, 1 is opaque //
// <pb> - Page break //
// <font> - Set the font for the following text. Options are: //
// face=<face name> //
// size=<point size> //
// style=r/b/i/bi //
// color=rrggbb - Hex color //
// spacing=<pixels> - line spacing in pixels //
// <cover> - Optionally sets the cover mipmap for the book. //
// src=<mipmap name> - Selects the mipmap to be used, using the //
// same search methods as <img>. Unlike <img> //
// though, <cover> has no restriction on //
// mipmap format. //
// tint=rrggbb - Hex color for tinting the cover image //
// tintfirst=yes/no - Tint the cover before applying decals, //
// defaults to yes. A no option overrides the //
// individual tint options on the <decal> tags //
// <margin> - Optionally sets the margin size in pixels, default is 16 //
// top=<size> //
// left=<size> //
// bottom=<size> //
// right=<size> //
// <book> - Optionally sets the size of the book in percent (0-1), //
// can be overridden by the SetBookSize funtion. //
// height=<size> //
// width=<size> //
// <decal> - Optionally specifies a decal to be drawn on the cover in //
// the specified position. Options are: //
// src=<mipmap name> - Selects the mipmap to be used, using the //
// same search methods as <imp>. Unlike <img> //
// though, <decal> has no restrictions on //
// mipmap format. //
// pos=<x>,<y> - Specifies the position of the decal on the //
// cover using the upper-left pixel //
// align=left/right/center //
// - Aligns the decal horizontally, overriding //
// any x coord in the pos option, if no y has //
// been specified, then it places it at the //
// top of the cover //
// resize=yes/no - Defines whether the image will be resized //
// with the book or not, defaults to yes //
// tint=yes/no - Defines whether or not this decal is tinted //
// with the cover. Overridden by the tintfirst //
// option on the <cover> tag. Defaults to no //
// <movie> - Places a movie (.bik file) inline with the text. Options: //
// src=<movie name> - Selects the movie to be used. (nead search //
// methods here eventually) //
// align=left/right/center //
// - Aligns the movie horizontally, overriding //
// any x coord in the pos option //
// link=<eventID> - Defines the movie as clickable. When the //
// User clicks the movie, it will generate an //
// event with the given event ID and send it //
// to the calling python handler //
// pos=<x>,<y> - Specifies the position of the movie on the //
// page using the upper left pixel given, does //
// not influence text flow //
// resize=yes/no - Defines whether the movie will be resized //
// with the book or not, defaults to yes //
// oncover=yes/no - Defines whether the movie will be placed on //
// the cover or not, defaults to no. NOTE: //
// setting this to yes causes the link option //
// to be ignored since cover movies can't link //
// loop=yes/no - Defines whether the movie will loop or not //
// defaults to yes //
// <editable> - Marks this book as editable (if the GUI supports it) //
// //
// The pages don't render until displayed. As a result, jumping to a given //
// page requires each page from the current position to the destination //
// to be rendered. Normally, this won't be a problem, because by default //
// books open to the first page, at which point each page renders one //
// at a time as the user flips through. //
// //
// The system assumes that no more than one book will ever actually be //
// shown at any time. As a result, the internal geometry for displaying //
// each book can be shared, reducing overhead and potential for errors. //
