#Struct SkRect

#Code
#Populate
##

SkRect holds four SkScalar coordinates describing the upper and
lower bounds of a rectangle. SkRect may be created from outer bounds or
from position, width, and height. SkRect 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.

# move to topic about MakeIWH and friends
SkRect can be constructed from int values to avoid compiler warnings that
integer input cannot convert to SkScalar without loss of precision.

#Member SkScalar  fLeft
#Line # smaller x-axis bounds ##
May contain any value, including infinities and NaN. The smaller of the
horizontal values when sorted. When equal to or greater than fRight, Rect is empty.
##

#Member SkScalar  fTop
#Line # smaller y-axis bounds ##
May contain any value, including infinities and NaN. The smaller of the
vertical values when sorted. When equal to or greater than fBottom, Rect is empty.
##

#Member SkScalar  fRight
#Line # larger x-axis bounds ##
May contain any value, including infinities and NaN. The larger of the
horizontal values when sorted. When equal to or less than fLeft, Rect is empty.
##

#Member SkScalar  fBottom
#Line # larger y-axis bounds ##
May contain any value, including infinities and NaN. The larger of the
vertical values when sorted. When equal to or less than fTop, Rect is empty.

#Subtopic Intersection
#Line # sets to shared bounds ##

Rects intersect when they enclose a common area. To intersect, each of the pair
must describe area; fLeft is less than fRight, and fTop is less than fBottom;
isEmpty() returns false. The intersection of Rect pair can be described by:
#Formula # (max(a.fLeft, b.fLeft), max(a.fTop, b.fTop),
            min(a.fRight, b.fRight), min(a.fBottom, b.fBottom)) ##.

The intersection is only meaningful if the resulting Rect is not empty and
describes an area: fLeft is less than fRight, and fTop is less than fBottom.
