Corrects a bug in an font scaling test that assumed the test host had its
content sizes category set to `UIContentSizeCategoryLarge`.
Discovered while authoring #8476.
This method's logic exists frequently throughout our componentry and theming extensions as a mechanism for scaling a scalable font with the preferred content size category.
This change introduces a new API that can be invoked by each of the components and theming extensions that support Dynamic Type.
Part of https://github.com/material-components/material-components-ios/issues/7470
Prior to this change, mdc_scalingCurve was implemented using retain semantics insteaad of copy semantics. This potentially enabled a class of surprising bugs if mutable dictionaries were being assigned and then modified after the fact.
After this change, mdc_scalingCurve implements copy semantics as its public API defines.
The added test was verified to fail prior to this PR's change, and passes with the PR's change.
Closes https://github.com/material-components/material-components-ios/issues/7472
Adds a new scheme that vends fonts with an associated scaling curve.
This is a BREAKING CHANGE due to a new, required property in the MDCTypographyScheming protocol.
To easily migrate, clients can add the following method to their custom implementations of MDCTypographyScheming.
- (BOOL)mdc_adjustsFontForContentSizeCategory {
return NO;
}
MDCFontScalar allows us to add an associated scaling curve to UIFont instances. This scaling curve allows us to support Dynamic Type by creating differently sized fonts based on a UIContentSizeCategory.
MDCFontScaler offers similar, but limited, functionality as UIKit's UIFontMetrics.
Replacing all non-integral, single-precision floating point literals with double-precision values explicitly cast to CGFloat. For example, `0.1f` should become `(CGFloat)0.1`.

`- UIFont systemFontOfSize:weight:` was not introduced until iOS 8.2. Although
most of the code was already performing runtime checks on the selector, the
compiler still emits warnings for the use of the selectors.
Closes 2779

* [Typography] added boldItalic font to optional protocol of the TypographyFontLoading protocol
* revert cocoa pods version number
* fixed bold/regular variable name
* added comment for font size must be greater than 0
* [Typography] Added isLargeForContrastRatio so that we can make the font tell us if it is has large fonts.
* lint
* added fuller doc
* fixed system font loader to return optional protocol method isLargeForContrastRatio
* removed class method
* moved bold and italic to be optional properties.
* Update MDCTypography.m
* added UIFontWeightMedium weak check.
* [Typography] Removes the runtime inspection that uses Roboto if it can be found (via MDCRobotoFontLoader) (#712)
* [Typography] Removed runtime inspection for MDCRobotoFontLoader and using Roboto if found.

Summary:
internal reference: cl/121301531
- Renamed some of the FontDiskLoader's APIs to be more readable.
- |registerFont| renamed to |load|
- |unregisterFont| renamed to |unload|
- |isRegistered| renamed to |loaded|
- Made FondDiskLoader thread safe.
- Made fontName and fontURL copy, readonly, nonnull properties.
- More comments across the board and other miscellaneous Objective C Readability issues.
- Readded to be deprecated setFontName and other APIs.
Internal implementation detail refactors:
- Removed references to 'resource' as that was part of the old name of the FontDiskLoader class.
- Using dispatch queue for |loaded| protection instead of @syncronized. Also using class method for |setLoaded|.
- Fixed tests to make them not set the name of the font
- Added more descriptive messages for tests

We can credit any contributor who would like to be credited this way, by adding them on request to the AUTHORS file. The copyright statement changes are required for this to work. Note that this has no legal change, since the contributors always retained their copyright despite the copyright notice, but it's a nice acknowledgement.
