Support transparent background color

• Support transparent background color by specifying .backgroundColor(nil)

Image sizing bug & custom image sizing

• Fixes bug when an image changes the size of the document
• It adds ImageSizer protocol to allow custom image sizing, such as scaling to fit the width of the document

Fix regression on custom fonts not retaining weight

Full fix for #10

Fix custom fonts

Fixes certain custom fonts, like Avenir-Roman and Avenir-Medium that would revert to the "base" font (e.g. Avenir-Book).

Fix Bold and Italic on custom fonts

Fix bold and italic on custom fonts. This required removing NativeFontWeight type since it only worked on system fonts. The removal of the type is theoretically a breaking changing, so bumping this up a major version number. However, bold functionality is available by using the FontTraits type (which works on system and custom fonts).

armv7 build error

This release fixes a build error for projects that include the armv7 architecture.

SwiftUI & iOS 14 bugs

Changes

• Brought back the SwiftUI wrappers. Put in some workarounds to make them work as expected
• Fixed iOS/tvOS 14 bug where inline backgrounds -- such as those used by inline code spans -- didn't render.

Public release

Changes

• Improved the document (which is still light, but probably enough to be useful)
• Remove NativeMarkText because the iOS version can't be made to work
• Tiny re-working on custom font specification to reduce boilerplate

Initial version

This is the first tagged release of NativeMarkKit!

What's working

• NativeMarkLabel
• StyleSheets
• All of the parsing and rendering for NativeMark
• NativeMarkText (aka SwiftUI) for macOS
• Dark mode
• Dynamic Type

What needs work still

• NativeMarkText for UIKit doesn't size properly if the text wraps
• Documentation is exceedingly light
• NativeMarkString/NativeMarkStorage/NativeMarkLayoutManager/NativeMarkTextContainer` all work for how NativeMarkKit use them internally, but haven't been vetted to see how generally useful they are
• Dark Mode on Mojave is mostly, but not completely supported. Mojave is missing APIs to add custom colors that automatically change between dark mode/light mode
