This is a complete set of layout rules, the 'state' of the Layout Engine. Multiple styles are possible, defined via C or Python. Styles get a name, and will typically get activated per region type, like Header, or Listview or Toolbar. Properties of Style definitions are:

default column properties, internal spacing, aligning, min/max width
button alignment rules (for groups)
label placement rules
internal labeling or external labeling default
default minimum widths for buttons/labels (in amount of characters)
font types, styles and relative sizes for Panel titles, labels, etc.

◆ uiStyleInit()

void uiStyleInit ( )

Called on each startup.blend read, reading without uiFont will create one.

Second for rendering else we get threading problems,

Note: This isn't good that the render font depends on the preferences, keep for now though, since without this there is no way to display many unicode chars.
