+not support transparency because of limitations of the underlying libraries.
+Printer and WMF drawers can not support transparency in principle.&lt;/p&gt;
+  <p/><p><b>Optimization note:</b> Transparency support in the LCL is rudimentary.
+The current TCanvas drawer implementation, therefore, may be slow with many transparent
+series and large charts. To improve efficiency, it is recommended to use as
+few different transparency levels as possible and to not interleave series
+with different transparencies. Alternatively, use BGRABitmap as back-end,
+since it has a faster transparency implementation.</p>
