- * Modern TrueType fonts are usually rendered through Microsoft's
- * collection of rendering techniques called ClearType (e.g., subpixel
- * rendering and subpixel hinting). When ClearType was introduced, most
- * fonts were not ready. Microsoft decided to implement a backward
- * compatibility mode that employed several simple to complicated
- * assumptions and tricks that modified the interpretation of the
- * bytecode contained in these fonts to make them look ClearType-y
- * somehow. Most (web)fonts that were released since then have come to
- * rely on these hacks to render correctly, even some of Microsoft's
- * flagship ClearType fonts (Calibri, Cambria, Segoe UI).
+ * FreeType supports ClearType-like hinting of TrueType fonts through
+ * the version 40 interpreter. This is achieved through several hacks
+ * in the base (v35) interpreter, as detailed below.
*
- * The minimal subpixel hinting code (interpreter version 40) employs a
- * small list of font-agnostic hacks to bludgeon non-native-ClearType
- * fonts (except tricky ones[1]) into submission. It will not try to
- * toggle hacks for specific fonts for performance and complexity
- * reasons. The focus is on modern (web)fonts rather than legacy fonts
- * that were made for black-and-white rendering.
+ * ClearType is an umbrella term for several rendering techniques
+ * employed by Microsoft's various GUI and rendering toolkit
+ * implementations, most importantly: subpixel rendering for using the
+ * RGB subpixels of LCDs to approximately triple the perceived
+ * resolution on the x-axis and subpixel hinting for positioning stems
+ * on subpixel borders. TrueType programming is explicit, i.e., fonts
+ * must be programmed to take advantage of ClearType's possibilities.
+ *
+ * When ClearType was introduced, it seemed unlikely that all fonts
+ * would be reprogrammed, so Microsoft decided to implement a backward
+ * compatibility mode. It employs several simple to complicated
+ * assumptions and tricks, many of them font-dependent, that modify the
+ * interpretation of the bytecode contained in these fonts to retrofit
+ * them into a ClearType-y look. The quality of the results varies.
+ * Most (web)fonts that were released since then have come to rely on
+ * these hacks to render correctly, even some of Microsoft's flagship
+ * fonts (e.g., Calibri, Cambria, Segoe UI).
+ *
+ * FreeType's minimal subpixel hinting code (interpreter version 40)
+ * employs a small list of font-agnostic hacks loosely based on the
+ * public information available on Microsoft's compatibility mode[2].
+ * The focus is on modern (web)fonts rather than legacy fonts that were
+ * made for monochrome rendering. It will not match ClearType rendering
+ * exactly. Unlike the `Infinality' code (interpreter version 38) that
+ * came before, it will not try to toggle hacks for specific fonts for
+ * performance and complexity reasons. It will fall back to version 35
+ * behavior for tricky fonts[1] or when monochrome rendering is
