#Struct SkIRect

#Code
#Populate
##

SkIRect holds four 32-bit integer coordinates describing the upper and
lower bounds of a rectangle. SkIRect may be created from outer bounds or
from position, width, and height. SkIRect 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.

#Member int32_t  fLeft
#Line # smaller x-axis bounds ##
May contain any value. The smaller of the horizontal values when sorted.
When equal to or greater than fRight, IRect is empty.
##

#Member int32_t  fTop
#Line # smaller y-axis bounds ##
May contain any value. The smaller of the horizontal values when sorted.
When equal to or greater than fBottom, IRect is empty.
##

#Member int32_t  fRight
#Line # larger x-axis bounds ##
May contain any value. The larger of the vertical values when sorted.
When equal to or less than fLeft, IRect is empty.
##

#Member int32_t  fBottom
#Line # larger y-axis bounds ##
May contain any value. The larger of the vertical values when sorted.
When equal to or less than fTop, IRect is empty.

#Method static constexpr SkIRect MakeEmpty()

#In Constructors
#Line # returns bounds of (0, 0, 0, 0) ##
Returns constructed IRect 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.

#Return bounds (0, 0, 0, 0) ##

#Example
    SkIRect rect = SkIRect::MakeEmpty();
    SkDebugf("MakeEmpty isEmpty: %s\n", rect.isEmpty() ? "true" : "false");
    rect.offset(10, 10);
    SkDebugf("offset rect isEmpty: %s\n", rect.isEmpty() ? "true" : "false");
    rect.inset(10, 10);
    SkDebugf("inset rect isEmpty: %s\n", rect.isEmpty() ? "true" : "false");
    rect.outset(20, 20);
    SkDebugf("outset rect isEmpty: %s\n", rect.isEmpty() ? "true" : "false");
#StdOut

may be negative.

#Param w  width of constructed IRect  ##
#Param h  height of constructed IRect ##

#Return bounds (0, 0, w, h) ##

#Example

#Subtopic Inset_Outset_Offset ##

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

IRects 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;
empty() returns false. The intersection of IRect 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 IRect is not empty and
describes an area: fLeft is less than fRight, and fTop is less than fBottom.

#Method void adjust(int32_t dL, int32_t dT, int32_t dR, int32_t dB)

#In Inset_Outset_Offset
#Line # moves the sides independently relative to their original locations ##
Adjusts IRect by adding dL to fLeft, dT to fTop, dR to fRight, and dB to fBottom.

If dL is positive, narrows IRect on the left. If negative, widens it on the left.
If dT is positive, shrinks IRect on the top. If negative, lengthens it on the top.
If dR is positive, narrows IRect on the right. If negative, widens it on the right.
If dB is positive, shrinks IRect on the bottom. If negative, lengthens it on the bottom.

The resulting IRect is not checked for validity. Thus, if the resulting IRect left is
greater than right, the IRect will be considered empty. Call sort() after this call
if that is not the desired behavior.

#Param dL  offset added to fLeft ##
#Param dT  offset added to fTop ##
#Param dR  offset added to fRight ##
#Param dB  offset added to fBottom ##

#Method static bool Intersects(const SkIRect& a, const SkIRect& b)

#In Intersection
#Line # returns true if areas overlap ##
Returns true if a intersects b.
Returns false if either a or b is empty, or do not intersect.

#Param a  IRect to intersect ##
#Param b  IRect to intersect ##

#Return true if a and b have area in common ##

#Example
    SkDebugf("%s intersection", SkIRect::Intersects({10, 40, 50, 80}, {30, 60, 70, 90}) ? "" : "no ");

#Method static bool IntersectsNoEmptyCheck(const SkIRect& a, const SkIRect& b)

#In Intersection
#Line # returns true if areas overlap skips empty check ##
Returns true if a intersects b.
Asserts if either a or b is empty, and if SK_DEBUG is defined.

#Param a  IRect to intersect ##
#Param b  IRect to intersect ##

#Return true if a and b have area in common ##

#Example

#Method void join(int32_t left, int32_t top, int32_t right, int32_t bottom)

#In Join
#Line # sets to union of bounds ##
Constructs IRect to intersect from (left, top, right, bottom). Does not sort
construction.

Sets IRect to the union of itself and the construction.

Has no effect if construction is empty. Otherwise, if IRect is empty, sets
IRect to construction.

#Param left  x-axis minimum of constructed IRect ##
#Param top  y-axis minimum of constructed IRect ##
#Param right  x-axis maximum of constructed IRect ##
#Param bottom  y-axis maximum of constructed IRect ##

#Example
    SkIRect rect = { 10, 20, 15, 25};
    rect.join(50, 60, 55, 65);
    SkDebugf("join: %d, %d, %d, %d\n", rect.fLeft, rect.fTop, rect.fRight, rect.fBottom);
#StdOut

#Method void join(const SkIRect& r)

#In Join
Sets IRect to the union of itself and r.

Has no effect if r is empty. Otherwise, if IRect is empty, sets IRect to r.

#Param r  expansion IRect ##

#Example
    SkIRect rect = { 10, 20, 15, 25};
    rect.join({50, 60, 55, 65});
    SkDebugf("join: %d, %d, %d, %d\n", rect.fLeft, rect.fTop, rect.fRight, rect.fBottom);

#Subtopic Sorting

#Method void sort()

#In Sorting
#Line # orders sides from smaller to larger ##
Swaps fLeft and fRight if fLeft is greater than fRight; and swaps
fTop and fBottom if fTop is greater than fBottom. Result may be empty,
and width() and height() will be zero or positive.

#Example
    SkIRect rect = { 30, 50, 20, 10 };
    SkDebugf("rect: %d, %d, %d, %d\n", rect.fLeft, rect.fTop, rect.fRight, rect.fBottom);
    rect.sort();
    SkDebugf("sorted: %d, %d, %d, %d\n", rect.fLeft, rect.fTop, rect.fRight, rect.fBottom);
#StdOut
rect: 30, 50, 20, 10
sorted: 20, 10, 30, 50

#Method SkIRect makeSorted() const

#In Sorting
#In Constructors
#Line # constructs IRect, ordering sides from smaller to larger ##
Returns IRect with fLeft and fRight swapped if fLeft is greater than fRight; and
with fTop and fBottom swapped if fTop is greater than fBottom. Result may be empty;
and width() and height() will be zero or positive.

#Return  sorted IRect ##

#Example
    SkIRect rect = { 30, 50, 20, 10 };
    SkDebugf("rect: %d, %d, %d, %d\n", rect.fLeft, rect.fTop, rect.fRight, rect.fBottom);

#Method static const SkIRect& EmptyIRect()

#In Constructors
#Line # returns immutable bounds of (0, 0, 0, 0) ##
Returns a reference to immutable empty IRect, set to (0, 0, 0, 0).

#Return  global IRect set to all zeroes ##

#Example
    const SkIRect& rect = SkIRect::EmptyIRect();
    SkDebugf("rect: %d, %d, %d, %d\n", rect.fLeft, rect.fTop, rect.fRight, rect.fBottom);
