972 * MatIconRegistry. If the svgIcon value contains a colon it is assumed to be in the format

974 * Examples:
975 * `<mat-icon svgIcon="left-arrow"></mat-icon>
976 * <mat-icon svgIcon="animals:cat"></mat-icon>`
977 *
978 * - Use a font ligature as an icon by putting the ligature text in the content of the `<mat-icon>`
979 * component. By default the Material icons font is used as described at
980 * http://google.github.io/material-design-icons/#icon-font-for-the-web. You can specify an
981 * alternate font by setting the fontSet input to either the CSS class to apply to use the
982 * desired font, or to an alias previously registered with MatIconRegistry.registerFontClassAlias.
983 * Examples:
984 * `<mat-icon>home</mat-icon>
985 * <mat-icon fontSet="myfont">sun</mat-icon>`
986 *
987 * - Specify a font glyph to be included via CSS rules by setting the fontSet input to specify the
988 * font, and the fontIcon input to specify the icon. Typically the fontIcon will specify a
989 * CSS class which causes the glyph to be displayed via a :before selector, as in
