<h1><a name="rect">module: rect</a></h1><p><b>Basic rectangle handling</b><p>

This module contains typedefs, functions and macros for handling
rectangles.  Also included are macros to determine intersections and unions
areas.

<a name="MX_RECT"><code>MX_RECT</code></a>
<p>
<p><b>A basic rectangle</b><p>
This type is a basic rectangle with an upper-left at x1,y1 and 
lower-right at x2, y2.  
(<a href="../include/deds/rect.h">../include/deds/rect.h</a>)
<p>member: <b>
		int x1</b> Left coordinate  
(<a href="../include/deds/rect.h">../include/deds/rect.h</a>)
<p>member: <b>
		int y1</b> Upper coordinate  
(<a href="../include/deds/rect.h">../include/deds/rect.h</a>)
<p>member: <b>
		int x2</b> Right coordinate

<li>
<a name=" define MXRECT_VALID(A)"><code># define MXRECT_VALID(A)</code></a>
<p>
<p><b>Is MX_RECT valid?</b><p>
This macro returns non-zero if the upper-left of the rectangle is 
above and to the right of the lower-left of the rectangle, zero otherwise.  
(<a href="../include/deds/rect.h">../include/deds/rect.h</a>)<p></li>
<li>
<a name=" define MXRECT_INTERSECT(A, B, R)"><code># define MXRECT_INTERSECT(A, B, R)</code></a>
<p>
<p><b>Find intersection of two rectangles</b><p>
This macro finds the intersection of two rectangles.  
(<a href="../include/deds/rect.h">../include/deds/rect.h</a>)<p></li>
<li>
<a name=" define MXRECT_UNION(A, B, R)"><code># define MXRECT_UNION(A, B, R)</code></a>
<p>
<p><b>Union of two rectangles.  </b><p>
(<a href="../include/deds/rect.h">../include/deds/rect.h</a>)<p></li>
<li>
<a name=" define MXRECT_CONTAINS(R, X, Y)"><code># define MXRECT_CONTAINS(R, X, Y)</code></a>
<p>
<p><b>Point contained in MX_RECT</b><p>
This macro return non-zero if a given x,y point is indose the 
rectangel error, zero otherwise.  
(<a href="../include/deds/rect.h">../include/deds/rect.h</a>)<p></li>
<li>
<a name=" define MXRECTS_OVERLAP(A, B)"><code># define MXRECTS_OVERLAP(A, B)</code></a>
<p>
<p><b>Do MX_RECT overlap?</b><p>
This macro return non-zero if two rectangels overlap, zero otherwise.  
(<a href="../include/deds/rect.h">../include/deds/rect.h</a>)<p></li>
<li>
<a name="void mx_rect_move(MX_RECT* rrect, int x, int y)"><code>void mx_rect_move(MX_RECT* rrect, int x, int y)</code></a>
<p>
<p><b>Move a MX_RECT</b><p>
This function moves a MX_REXT so that the upper left of the rectangle 
is at a given x,y, position.  The size of the rectangle is not changed.  
(<a href="../include/deds/rect.c">../include/deds/rect.c</a>)<p></li>
<li>
<a name="void mx_rect_resize(MX_RECT* rrect, int w, int h)"><code>void mx_rect_resize(MX_RECT* rrect, int w, int h)</code></a>
<p>
<p><b>Resize a MX_RECT</b><p>
This function resizes a MX_REXT to a given size.  The upper left point 
of the rectangle does not change.
