Migrating to v2

Breaking Changes

Goki-wide

• Import paths have been changed from github.com/goki/* to goki.dev/* (for example, github.com/goki/gi changed to goki.dev/gi). All repositories with a changed import URL that were on version 1 are now on version 2 and have a major version URL suffix (for example, goki.dev/gi/v2)
• KiT_* global variables have been renamed to Type* (for example, KiT_Button changed to TypeButton); fixing this should be a simple find and replace for KiT_ => Type
• AddNew* functions and methods have been renamed to New* (for example, AddNewButton changed to NewButton); fixing this should be a simple find a replace for AddNew => New

goki/ki

• Package ki has been moved into the root directory of ki, so it is now imported as just goki.dev/ki/v2
• Support for automatic Ki field children has been removed, so you now have to manage that yourself (see https://github.com/goki/ki/issues/17)

goki/gi/gi

• Defaults() method removed on several widgets (slider, spinbox, scrollbar, etc); it is no longer needed and all calls of it can be deleted.
• MenuButton widget removed; use Button instead, as you can put a menu on any button. If you want the arrow indicator again, put button.Indicator = icons.KeyboardArrowDown
• Action and ButtonBase removed; use Button instead.
• Inactive renamed to Disabled and Active to Enabled. Many node flag functions (eg, SetInactive, IsActive, etc) as well as the actual enum constants must be renamed.
• ClearAct field on TextField converted to LeadingIcon and TrailingIcon; use AddClearAction() to easily replicate the same functionality.
• gi.IconName removed and replaced with icons.Icon; many functions and fields have changed types that must be updated; also, previous icon names may be broken or have changed to new icons, and it is strongly recommended that you use the new icon constants instead of untyped string literals.
• Prop-based styling and configuration removed; set the Style field using AddStyleFunc for styling and directly set the configuration struct fields in your code for configuration.
• Prefs colors removed; use gi.ColorScheme instead.

goki/gi/gist

• Color transformation functions like Highlight now take non-pointer receivers to support function chaining.

goki/gi/units

• units.New* functions have been renamed to units.* (for example, units.NewPx changed to units.Px); fixing this should be a simple find and replace for units.New (although if you use units.NewValue, which is unchanged, you will have to avoid changing that).
• Renamed (units.Context).ToDotsFactor to (units.Context).Dots
• Removed units.Pct and related things (replaced with units.Ew, units.Eh, units.Pw, units.Ph, and related things)
• Renamed units.Context fields ElW, ElH, VpW, and VpH to Ew, Eh, Vw, and Vh respectively.
• Setter functions for units.Context now also take parent size.
• units.Value contains a DotsFunc function (you should use keyed struct literals).
