Create methods which allow a graphics context to be created with a
CGContext as an equivalent to a graphics port. The context set through
this property will be used in gnustep-back.
Expose methods for bridging Opal types and GUI classes. The new
relations are the following:
a) NSImage -> CGImage
b) NSColor -> CGColor
c) NSImageRep -> CGImage
The actual implementation for this bridge is implemented in the Backend
library.
This significantly improves compatibility with AppKit.
Objective-C memory management policy specifies that methods named with
alloc, new, copy and mutableCopy are the ones that return objects with
refcount 1.
Additionally, `@property (..., copy, ...)` only modifies the setter; the getter
still returns the object as-is. While it should be correct to create
a new immutable object every time, we should not create an object
with refcount 1, but an autoreleased object.
Implement the NSPasteboardItem class. For now, it remains relatively
useless since NSPasteboard does not yet know how to use it. However, it
should be pluggable into NSPasteboard once NSPasteboard learns about
NSPasteboardReading and NSPasteboardWriting.
As of macOS 10.7, scrollers gained two types: Legacy and Overlay. Here,
we define these styles as well as a method to determine which is the
"default" style to be used.
Declare base NSAccessibility functions and constants, which have been
implemented as stubs.
In the near future, we could begin supporting some NSAccessibility
informal protocol features (for instance, elements ignored in the
accessible view hierarchy). However, for even considering thorough
accessibility support we would require, at least:
* A proper implementation of the AX* API in gnustep-boron;
* Design integration with screen reading software and other components
for an accessible graphic environment.
which are most certainly long-term tasks.
Define layer-related properties in NSView for compatibility purposes,
and keep their getters and setters as stubs, since they will not have
any effect before NSView-CALayer integration is implemented.
Define new constants for NSPasteboard type identifiers. Most of them are
aliases to the old "Pboard"-style types, although some new ones are not
fully implemented:
* NSPasteboardTypePNG
* NSPasteboardTypeSound
* NSPasteboardTypeMultipleTextSelection
* NSPasteboardTypeTextFinderOptions
Modern applications require NSSpeechSynthesizerDelegate to be an actual
@protocol in order to conform to it. Here, we allow it to be one if we
are on an Objective-C runtime that supports it.
