We currently use code points as glyph codes for rendering purposes which leads to numerous rendering issues. Once Prism has glyph rendering API we should switch to it.

I think it is worth declaring com.sun.javafx.webkit.prism.TextUtilities class final and com.sun.javafx.webkit.prism.TextUtilities methods package private.

Pushed with Vasiliy's suggested changes: http://jfxsrc.us.oracle.com/javafx/8.0/scrum/graphics/rt-closed/rev/f33b53ad2727 http://jfxsrc.us.oracle.com/javafx/8.0/scrum/graphics/webnode/rev/aacbbfa61865

Fix was slightly modified after Felipe's comments. I've simplified TextUtilities.createLayout() and added a new method TextUtilities.createGlyphList() which is called from WCGraphicsPrismContext. Class TextLine is no longer used. http://javaweb.us.oracle.com/jcg/fx-webrevs/RT-24772/2

Suggested fix: http://javaweb.us.oracle.com/jcg/fx-webrevs/RT-24772/1 Summary of changes: - GlyphPage::fill() now simply passes characters array to Java where they are fed to CharToGlyphMapper. The rest of the method is rewritten after Chromium; - Methods in WCFontImpl that work with complex scripts were rewritten using TextLayout. getStringLength() was renamed getStringWidth(); - WCGraphicsPrismContext.drawString() renders GlyphLists instead of Strings.

Parts of RT-24327 should be rolled back once this is fixed, in particular the typedef in Glyph.h.
