[ros-kernel] RECT macros question

[Royce Mitchell III]

Hi guys,

Do we already have macros that do this, and where are they? ( Or if we 
don't have them, what should I name them and where should I put them? ) 
I want to use these in win32k, but I imagine they'd be useful in gdi32, too.

#define IN_RECT(r,x,y) \
( \
  (x) >= (r).left && \
  (y) >= (r).top && \
  (x) < (r).right && \
  (y) < (r).bottom \
)

#define RECT_OVERLAP(a,b) \
( \
   (a).left < (b).right && \
   (b).left < (a).right && \
   (a).top < (b).bottom && \
   (b).top < (a).bottom \
)
