cUITheme controls creation methods completed.
Fixed Font shadow drawing for cached fonts.
Fixed a bug on size calculation in GetSkinShapeSize on cUIControl.
Created a backend system for the window-input management. So now it will be a los easier to port to another windows library/platform.
Since this is a big commit, it's probably that some bugs where introduced, but i tested all that i could, and it's working fine.
I'll probably add a cursor manager backend because right now there is no cursor management at all, i removed the CreateCursor function because it was unusable.
Now the user can add new theme elements to search on the theme loading ( to be able to expand the themes without touching the source code of the library ).
Now the batch renderer is enabled by default ( before was forcing the renders always ). So i fixed all the bugs around this.
Fixed a bad texture rendering when tried to render in isometric mode and a sector of a texture.
Added Icon possibility to cUIPushButton.
Added default fonts for ui themes and global default font for all ui themes.
Changed how cUIGfx get shapes, now accept a new instance without shape.
Fixed how padding works on cUITextBox and cUITextInput.
Fixed font rendering in cTextCache when some text rendered with angle or/and scale ( it was breaking the model view matrix ).
Fixed a miscounting of the number of vertex for the cached text.
Fixed HaikuTTF destroy singleton ( now release fine the memory ).
Added some functions for tex env managing.
Modified some enum names from renders.
Added a pixel separator for characters in the ttf creation ( optional ).
Moved some OpenGL and GLEW things to cGL, this is for a future implementation with OpenGL ES and without GLEW.
Tryed to fix a bad rendering bug when clipping controls with borders ( borders disappear ), i think that the hack is working.
Modified some name conventions.
Added a Font Manager.
cShaderProgramManager is now using the tResourceManager.
Added support for Font async loading.
Changed Write overloading on cLog, for Writef, to avoid overloading errors.
