 /*!
+    \qmlproperty int QtQuick::Text::renderTypeQuality
+
+    Override the default rendering type quality for this component. This is a low-level
+    customization which can be ignored in most cases. It currently only has an effect
+    when \l renderType is \c Text.QtRendering.
+
+    The rasterization algorithm used by Text.QtRendering may give artifacts at
+    large text sizes, such as sharp corners looking rounder than they should. If
+    this is an issue for specific text items, increase the \c renderTypeQuality to
+    improve rendering quality, at the expense of memory consumption.
+
+    The \c renderTypeQuality may be any integer over 0, or one of the following
+    predefined values
+
+    \list
+    \li Text.DefaultRenderTypeQuality (default) = -1
+    \li Text.LowRenderTypeQuality = 26
+    \li Text.NormalRenderTypeQuality = 52
+    \li Text.HighRenderTypeQuality = 104
+    \li Text.VeryHighRenderTypeQuality = 208
