-throw out tools from "Demo" window to "Tools" window
-change ComboBox to Tabs for Tools
-Added more verbose tips
-Improved and fixed BrickBreaker collisions
-fixed simple DUB issue
-added support for multithreaded rendering (fast)
-improved shaders
-added support for rendering depth
-added rendering color support
-improved DeptThreadPool (dynamics setting number of tryWait counts before TryWait. Low cpu usage with high responivity)
-added possibility to change number of threads
-Fixed performance issue with multithreading and rendering
-start making better shaders (by using many macros)
-speed up rendeing when maximum objects count was reached
-remove map rendering form Snake demo, and render entities by themself
-start adding depth and color rendering parameters
-added properly names to jobs (for debugging purpses)
-starts adding multithreaded rendering
-added some math to vectors
