Bug 1363097 - Convert font inspector to React/Redux.

Instead of passing in the object, pass in the functions that you will be calling. Usually this is in the form of onX where X is a handler event.

We should just pass onTextBoxContextMenu into the propTypes instead of object. You would destructure for { onTextBoxContextMenu } = this.props;

Add a new line before and after the if statement to separate the block from the rest.

We should be consistent and use the function shorthand 

isPanelActive() { .. }

Add checks for this.inspector.toolbox && this.inspector.toolbox.currentToolId === "inspector"

I don't think we need a dim, undim and clear function when we do this with react. We should call an update each time the sidebar panel is selected and update the view. The react components should naturally know there is nothing to display if the fonts prop is just an empty array and an appropriate no fonts available message should be displayed.

Use function shorthand: 

onNewNode() { .. }

This should simply be 
if (this.isPanelVisible()) {
 this.update(....)
}

I would remove undim and dim since this is unneccessary. Simply, call a single update and let the react view handle everything.

Remove this check for dim. Also, remove the css for dim/undim

previewText === "" is accounted for with !previewText.

you can simply pass in fonts

Keep this list alphabetically ordered. Move utils below reducers. You will find that new unit tests that are added in /tests/ are also added in a browser.ini file, and there is something that enforces that the list of files are alphabetically ordered.

We should probably just do querySelector() since we only expect one textinput for the font inspector panel.

The whole sidebar-panel for the fontinspector can be removed since addSidebarTab does this for us.

Move this before exports.grids to keep this alphabetically ordered.

Let's move these event listener removal before setting the variables to null.

Keep the propTypes alphabetically ordered, but with the handler (onX) functions at the bottom.

We can make the addEventListener into one line if we destruct let { onTextBoxContextMenu } = this.props

It would be good to break the render of individual components down a bit more to make this a lot more readable. For instance, we can have renderFontFormatURL, renderFontCSS, etc.

We can destructure would lessen some of the for us after line 24.

let { name, CSSFamilyName: cssFamilyName, .. } = font;

Go back to calling this.init() here, but add a new line after the reference declarations prior to calling this.init().

Move all these bindings in a block after the reference declarations in the constructor. Again add a new line after this.store and a new line after all these bindings to really just separate it to logical blocks.

Remove fonts. We shouldn't have to pass in the fonts since the fonts is part of the store, which is connected to the App.

We need to make sure we call this.fontinspector.destroy() in inspector.js#destroy()

I have found in my testing that we don't really have the theme-switched problem from commenting out this code. I believe we can remove all of this onThemeChanged code that was added as a result of https://bugzilla.mozilla.org/show_bug.cgi?id=1119149.

We should move the previewText and showAllFonts into the font redux store, and change how we do updates. Ideally, when we update the preview text in the react component, we call some like onPreviewTextChange, which will dispatch an action to update the store's previewText (string) or showAllFonts (boolean). We want to offload this to the redux store because we want to maintain the state in these stores.

We actually need to move this before the animationinspector is added to maintain the original tab order.

I found in my testing that the theme-switched problem does still exist (when you switch from light to dark theme, the previews aren't visible), and that the change to isPanelVisible() also broke onThemeChanged. It makes the update halt if you're not on the inspector, but to change the theme you need to be on the settings panel, so the colour of the preview doesn't update. If reverting the isPanelVisible change is OK, I can fix it.

Calling this.init() here causes an "Invariant Violation" React error. I thought it might have been because we also call init() in inspector.js, but the error still occurs with that commented out.

I get this change, but I don't think we should be passing in the inspector object as a prop to the react components, and listening to these events in the component. Was there any particular problem that we encounter that required this changed?

Create a new function (onPreviewFonts) in fonts.js and pass it in as a prop and call this.props.onPreviewFonts(value). In onPreviewFonts we should call dispatch and update(). In update, we can fetch the state from the store annd not worry about passing all these props around.

Same as above.

We should just grab showAllFonts and previewText from the store here.

I think I messed up here and was looking at the wrong thing, but the font inspector should be last panel (after the animation inspector).
