Stores viewport information.
Viewport in pixels.
[x, y, width height]
where (x, y)
is lower left corner.
The size of frame buffer in pixels.
The size of window in points.
Computes absolute transform for 2D graphics,
which uses a row major 2x3 matrix.
The origin is in the upper left corner of the viewport rectangle.
The x axis points to the right, and the y axis points down.
The units are in points (window coordinates).
It is assumed that the underlying coordinate system is normalized
with the origin in the center, such that (-1.0, 1.0)
in the
underlying coordinate system corresponds to the
upper left corner of the viewport.
Formats the value using the given formatter. Read more
