Data type: style

--Overview--

A style specifies how a [[type:field]] should look,
things like position, size, fonts, colors, etc.

Styles are part of the [[file:style triangle]]:
| Description		Looks			Data
| [[type:Game]]		[[type:Stylesheet]]	[[type:Set]]
| [[type:Field]]	'''Style'''		[[type:Value]]

--Positioning--

<img src="style-positioning.png" alt="" style="float:right;border:1px solid #ccc;"/>
A style specifies the position of a box for the content.
To specify the horizontal location ''two'' of @left@, @width@ and @right@ must be specified.

For example:
> left:  10
> width: 20
Implies that @right@ is 30 pixels if the card is 60 pixels wide.

Similairly:
> left: 10
> right: 30
Implies the @width@ is 20.

The same holds for the vertical location and size; @top@, @height@ and @bottom@.

--Rotation--
Some types of styles allow an @angle@ to be specified.
The angle gives a counter clockwise rotation in degrees of the ''contents'' of the box.

For example, a text field with style:
>example:
>	width: 60
>	height: 40
>	alignment: top left
Would, with different angles, look like:<br/>

--Properties--
! Property		Type					Default		Description
| @z index@		[[type:int]]				@0@		Stacking of this box, fields with a heigher @z index@ are placed on top of those with a lower index.
| @left@		[[type:scriptable]] [[type:double]]	''Required''	Distance between left edge of the box and the left of the card in pixels.
| @width@		[[type:scriptable]] [[type:double]]	''Required''	Width of the box in pixels.
| @right@		[[type:scriptable]] [[type:double]]	''Required''	Distance between right edge of the box and the right of the card in pixels.
| @top@			[[type:scriptable]] [[type:double]]	''Required''	Distance between top edge of the box and the top of the card in pixels.

| @visible@		[[type:scriptable]] [[type:boolean]]	@true@		Is this field visible at all?

The rest of the properties depend on the type of [[type:field]] this style is for.

| ^^^		@line height soft@	[[type:double]]		@1@		Multiplier for the line height of 'soft' line breaks. These are breaks caused by wrapping around lines that are too long.<br/>
		 			 			 		A line height of @0@ means all lines are in the same position, @1@ is normal behaviour, @2@ skips a line, etc.
| ^^^		@line height hard@	[[type:double]]		@1@		Multiplier for the line height of 'hard' line breaks. These are breaks caused by the enter key.
| ^^^		@line height line@	[[type:double]]		@1@		Multiplier for the line height of 'soft' line breaks. These are breaks caused by @"<line>\n</line>"@ tags.
| ^^^		@line height soft max@	^^^			''disabled''	When there is still vertical room in the text box, increase the line heights to at most these values to spread the text more evenly.
| ^^^		@line height hard max@	^^^			^^^		^^^
| ^^^		@line height line max@	^^^			^^^		^^^
| ^^^		@paragraph height@	[[type:double]]		''flexible''	The height of paragraphs. If specified, each paragraph is given this much space, and aligned inside that space as specified by @alignment@.<br/>
		 			 			 		A paragraph break is any line break that is not soft (i.e. caused by word wrap or a @"<soft>"@ break).
| ^^^		@mask@			[[type:filename]]	''none''	A mask that indicates where in the box text can be placed.<br/>
		 			 			 		Text is never put in black areas of the box:<br/>
