<a href='SkRect_Reference#SkRect'>SkRect</a> holds four <a href='undocumented#SkScalar'>SkScalar</a> coordinates describing the upper and
lower bounds of a rectangle. <a href='SkRect_Reference#SkRect'>SkRect</a> may be created from outer bounds or
from position, width, and height. <a href='SkRect_Reference#SkRect'>SkRect</a> describes an area; if its right
is less than or equal to its left, or if its bottom is less than or equal to
its top, it is considered empty.
<a href='SkRect_Reference#SkRect'>SkRect</a> can be constructed from int values to avoid compiler warnings that
integer input cannot convert to <a href='undocumented#SkScalar'>SkScalar</a> without loss of precision.<table style='border-collapse: collapse; width: 62.5em'>

</pre>
Returns constructed <a href='SkRect_Reference#SkRect'>SkRect</a> set to (0, 0, 0, 0).
Many other rectangles are empty; if left is equal to or greater than right,
or if top is equal to or greater than bottom. Setting all members to zero
is a convenience, but does not designate a special empty rectangle.

<a href='SkRect_Reference#Rect'>Rects</a> intersect when they enclose a common area. To intersect, each of the pair
