-// Scissoring
-//
-// Scissoring allows you to clip the rendering into a rectangle. This is useful for various

-// Paths
-//
-// Drawing a new shape starts with nvgBeginPath(), it clears all the currently defined paths.
-// Then you define one or more paths and sub-paths which describe the shape. The are functions
-// to draw common shapes like rectangles and circles, and lower level step-by-step functions,
-// which allow to define a path curve by curve.
-//
-// NanoVG uses even-odd fill rule to draw the shapes. Solid shapes should have counter clockwise
-// winding and holes should have counter clockwise order. To specify winding of a path you can
-// call nvgPathWinding(). This is useful especially for the common shapes, which are drawn CCW.
-//
-// Finally you can fill the path using current fill style by calling nvgFill(), and stroke it
-// with current stroke style by calling nvgStroke().
-//
-// The curve segments and sub-paths are transformed by the current transform.
-
-// Clears the current path and sub-paths.

-//
-// Text
-//
-// NanoVG allows you to load .ttf files and use the font to render text.
-//
-// The appearance of the text can be defined by setting the current text style
-// and by specifying the fill color. Common text and font settings such as
-// font size, letter spacing and text align are supported. Font blur allows you
-// to create simple text effects such as drop shadows.
-//
-// At render time the font face can be set based on the font handles or name.
-//
-// Font measure functions return values in local space, the calculations are
-// carried in the same resolution as the final rendering. This is done because
-// the text glyph positions are snapped to the nearest pixels sharp rendering.
-//
-// The local space means that values are not rotated or scale as per the current
-// transformation. For example if you set font size to 12, which would mean that
-// line height is 16, then regardless of the current scaling and rotation, the
-// returned line height is always 16. Some measures may vary because of the scaling
-// since aforementioned pixel snapping.
-//
-// While this may sound a little odd, the setup allows you to always render the
-// same way regardless of scaling. I.e. following works regardless of scaling:
-//
-//		const char* txt = "Text me up.";
-//		nvgTextBounds(vg, x,y, txt, NULL, bounds);
-//		nvgBeginPath(vg);
-//		nvgRoundedRect(vg, bounds[0],bounds[1], bounds[2]-bounds[0], bounds[3]-bounds[1]);
