Determine whether two floating point rectangles are equal, within a default
epsilon.
Rectangles are considered equal if both are not NULL and each of their x,
y, width and height are within SDL_FLT_EPSILON of each other. This is often
a reasonable way to compare two floating point rectangles and deal with the
slight precision variations in floating point calculations that tend to pop
up.
Note that this is a forced-inline function in a header, and not a public
API function available in the SDL library (which is to say, the code is
embedded in the calling program and the linker and dynamic loader will not
be able to find this function inside SDL itself).
