+/** Specialized interface for bitmaps containing half floats as their
+    color components. Half floats are 16 bit wide, and some high-end
+    GPUs already have them as supported frame buffer format. In
+    contrast to <type>XHalfFloatBitmap</type>, this interface only
+    permits read-only access.<p>
+
+    Use this interface for e.g. bitmaps that are calculated
+    on-the-fly, or that are pure functional, and thus cannot be
+    modified.<p>
+
+    If you get passed an instance of
+    <type>XHalfFloatReadOnlyBitmap</type> that also supports the
+    <type>XVolatileBitmap</type> interface, things become a bit more
+    complicated. When reading data, one has to check for both
+    <type>VolatileContentDestroyedException</type> and mismatching
+    <type>FloatingPointBitmapLayout</type> return values. If either of them
+    occurs, the whole bitmap read operation should be repeated.<p>

+        bitmap, the same scanline padding takes place as when the
+        whole bitmap is requested. Note: as we currently have no 16
+        bit float UNO data type, the values are transported as 16 bit
+        integers across the API (which requires casting on both
