v0.7.0-alpha.2: 0.7.0-alpha.2 — `TextInput` improvements

TextInput has gotten a massive boost, and is now a proper text editor. On top of that, its subclass, CodeInput is now available with optional syntax highlighting (a separate package is available on DUB: fluid-tree-sitter). Both are full in terms of completeness and behave a lot like native or well-known editors. This is a significant step forward and it highlights Fluid's possibilities and maturity as a general library.

0.7.0 is currently exactly equal to 0.6.0 in terms of commits, scoring 171 commits since 0.6.3, for a total of 342 commits since 0.5.2. Fluid has reached a milestone of 500 commits!

Further improvements may still be performed, for example selection may be moved to Text.

New features:

• ModuleView: New experimental and optional node for displaying Ddoc documentation with Fluid. Includes support for live, editable examples. Incomplete.
• ProgressBar: A new node for indicating progress.
• CodeInput: A new code editor node has been added, which supports syntax highlighting and automatic indents.
• Rope: Fluid now uses Rope instead of string in all context where text rendering is involved. This is a significant change as it greatly influences all workflow surrounding text rendering. However, it is in great compatibility with original strings, so in many scenarios the change is not noticeable.
• FluidScrollable: A new interface is available in fluid.scroll that makes it possible to define a scrollable node in a uniform manner.
• Text: Massive optimizations in terms of performance involving large amounts of text. Text will only be rasterized once it reaches the screen. Low level API is exposed through CompositeTexture.
• TextInput: Multiline TextInput is now available with the .multiline node property. A separate constructor may be added in the future.
• TextInput: The caret now can be moved using arrow keys or the mouse.
• TextInput: Text can now be selected, copied, pasted.
• TextInput: Support for undo and redo was added.
• Image & Texture: Images now support two new formats, and Textures support two corresponding rendering modes in order to support texture masks and palettes.
• TagList: New method remove can be used to remove tags.
• FrameButton: hframeButton is now available.

Removed features:

• SimpledisplayBackend has been removed. arsd.simpledisplay no longer supports the D language and has moved on to OpenD.

Deprecations:

• Grid has been renamed to GridFrame. (Thanks @LiamM32)
• frameButton has been renamed to vframeButton.

Improvements:

• The tour now has a separate DUB recipe.
• MapFrame: addChild will now fail contracts on null nodes.
• toFluid has been added to use Raylib textures in fluid.Texture contexts (Thanks @LiamM32).
• ImageView: Images can now be used directly with ImageView (Thanks @LiamM32).
• Raylib: Trilinear filtering is now used by default when rendering textures.
• MapFrame: addChild now has one more overload that supports Vector2 (Thanks @LiamM32)
• The showcase now defaults to Raylib, which is also now included in Fluid.
• FreetypeTypeface: advance result is now cached.
• Typeface.measure: New overload has been added to operate directly on TextRuler.
• Tree now uses a separate set of key bindings on macOS.
• Better Unicode test coverage for TextInput.
• PasswordInput: Shredding is now explicit.
• The showcase has been renamed to Tour and its directory has been renamed accordingly.

Bugfixes:

• SwitchSlot: Make sure the correct size is used if there are multiple references to a child. #138
• DragSlot: Ignore Style.gap for hidden handles.
• Space: Include Style.gap in minSize
• TextInput: Unicode related bugfixes
• Text: Bugfix multiline text not updating when changed.
• Possible use-after-free if TextureGC is used inside as a dynamic array element.
