Rendition at manifest level setup
Feature request There's no way to add at manifest level rendition properties (current realization supports only spine)
<meta property="rendition:layout">pre-paginated</meta>
<meta property="rendition:orientation">portrait</meta>
<meta property="rendition:spread">none</meta>
By the way, looks like current iBooks fails to read rendition set via properties in spine and works only with meta-section. And there's no need in setting up custom ibooks com.apple.blah-blah properties file in META-INF. Checkout this example http://files.infogridpacific.com/fxl-tb/fxl-portrait-locked-16x9.epub
Actually it doesn't work in elder ::Builder notation. But works this way
book = GEPUB::Book.new
book.set_primary_identifier('urn:uuid:'+uniqueid, 'pub-id', 'uuid')
book.language = @document.language
book.date = DateTime.now.strftime("%Y-%m-%dT%H:%M:%S%:z")
book.rendition_layout='pre-paginated'
book.rendition_orientation='landscape'
book.rendition_spread='false'
Hard to understand withot looking to the core: something sets as property, smth via setters etc
I admit the current API is rather confusing.
Current design is : attribute or metadata with single value sets as property assignment, and setting multiple value via setter (like set_primary_identifier).
