extra draw gui

Browse source 
add the extra functions for drawing gui elements
RoundedRectangle:

All draw rect functions now pass through roundedRectangle which uses a shader and can draw borders, and rounds the corners

Draw thick line:
draws a line thicker than 1 pixel, uses a geometry shader to do this

Draw Circle:
Draws a circle with a border parameter.
