From 8403dcf857c9cc639e8162edd5d4df4af07274bc Mon Sep 17 00:00:00 2001
From: Andrei Karas <akaras@inbox.ru>
Date: Sat, 26 Mar 2011 05:07:12 +0200
Subject: Precalculation vertexes for improving draw speed.

Implemented in Software and fast OpenGL backends.
Not all controls using this mode because some limitations.

Known issue: impossible compile without opengl.
Will be fixed in next commits.
