[IMPORTANT - NEED FEEDBACK] Major refactor, improvements, and optimization for v1.0.0

[flamendless]

Refactor and improvements include:

• reduce GC by not creating tables/strings when they can be reused
• consistent casing: snake_case for variables, PascalCase for methods
• abstraction of commonly used strings/types
• easier to read boolean evaluation (lua's ternary operation) for default values
• convert single-quote strings to double-quote strings

After refactoring:

• measure performance/garbage generated of both the old and new version for comparison

NOTE that these are internals thus wont be breaking changes for the users.

Im seriously thinking of changing the fields passed in table/option to widgets from PascalCase to snake_case to make it uniform, this would however lead to breaking changes and users will have to update all of their code to match the new casing. What do you users of Slab think of this? Please feel free to share your thoughts :)

Example of the change would be:

Slab.BeginWindow("id", {Title = "PascalCase Title", X = 0, Y = 0, AutoResizeWindow = true)})
--to
Slab.BeginWindow("id", {title = "snake_case title", x = 0, y = 0, auto_resize_window = true})

Development of v1.0.0 is taking a long break since I have been really busy with work + 3 side projects.

The only thing we are missing for this major release is some functionalities are not working anymore:

• resizing window
• moving/dragging window
• Almost every mouse interaction
• Button layout and rendering
• Checkbox layout and rendering

Tested widgets/UIs:

• Button
• CheckBox
• ColorPicker
• ComboBox
• Cursor
• Dialog
• Dock
• Image
• Input
• Interaction
• Layout
• ListBox
• Menus
• Messages
• Properties
• SaveState
• ScrollBar
• Separator
• Setup
• Shader
• Shape
• SlabDebug
• Stats
• Style
• Text
• Tooltip
• Tree
• Window

It would be great if someone can do a full test and list here the things that are broken so that other people can also help with the fixing. Thank you!

BREAKING CHANGES

The following now have the function signature (id, selected, opt)

• ComboBox
• ListBoxItem
• RadioButton

Example:

--before
if Slab.ComboBox("combobox", {Selected = "Apple"}) then end
--after
if Slab.ComboBox("combobox", "Apple"}) then end
