Major changes to UICircle with some member modifications and additions to the component behaviour.
* Added progress indicator capability to the component. * Component uses AddUIVertexStream to generate vertices and indices of triangle order. * Improves base geometry generation to prevent edge sliding on segment value changes (tris density, now called Arc Steps). * Corrects a minor issue with base mesh where first vertex is generate at center (only visable in wireframe mode at certain angles).release

///
|

/// * Modified component to utilize vertex stream instead of quads

/// * Improved accuracy of geometry fill to prevent edge "sliding" and redundant tris
|

/// * Added progress capability to allow component to be used as an indicator
|
||||
/// * Added methods for use during runtime and event system(s) with other components
|

/// * Change some terminology of members to reflect other component property changes
|

/// * Added padding capability
|

/// * Only utilizes UV0 set for sprite/texture mapping (maps UV to geometry 0,1 boundary)
|
||||
/// * Sample usage in scene "UICircleProgress"
|

/// Note: moving the pivot around from center to an edge can cause strange things

/// as well as having the RectTransform be smaller than the Thickness and/or Padding.
