||||||
* not consistent between Windows and UNIX/X11; since
|

* platform independence is a virtue for "freeglut", we
|

* decided to break with GLUT's behaviour.
|

*
|

* Under UNIX/X11, it is apparently not possible to get the

* window border sizes in order to subtract them off the

* window's initial position until some time after the window
|

||||||
* behaviour, both under Windows and under UNIX/X11:
|
|
||||||
* - When you create a window with position (x,y) and size
|
|
||||||
* (w,h), the upper left hand corner of the outside of the
|
|
||||||
* window is at (x,y) and the size of the drawable area is
|
|
||||||
* (w,h).
|
|
||||||
* - When you query the size and position of the window--as
|
|
||||||
* is happening here for Windows--"freeglut" will return
|
|
||||||
* the size of the drawable area--the (w,h) that you
|
|
||||||
* specified when you created the window--and the coordinates
|
|
||||||
* of the upper left hand corner of the drawable
|
|
||||||
* area--which is NOT the (x,y) you specified.

|

|
* There is considerable confusion about the "right thing to
|
||||||
|
* do" concerning window size and position. GLUT itself is
|
||||||
|
* not consistent between Windows and UNIX/X11; since
|
||||||
|
* platform independence is a virtue for "freeglut", we
|
||||||
|
* decided to break with GLUT's behaviour.
|
||||||
|
*
|
||||||
|
* Under UNIX/X11, it is apparently not possible to get the
|
||||||
|
* window border sizes in order to subtract them off the
|
||||||
|
* window's initial position until some time after the window
|
||||||
|
* has been created. Therefore we decided on the following
|
||||||
|
* behaviour, both under Windows and under UNIX/X11:
|
||||||
|
* - When you create a window with position (x,y) and size
|
||||||
|
* (w,h), the upper left hand corner of the outside of the
|
||||||
|
* window is at (x,y) and the size of the drawable area is
|
||||||
|
* (w,h).
|
||||||
|
* - When you query the size and position of the window--as
|
||||||
|
* is happening here for Windows--"freeglut" will return
|
||||||
|
* the size of the drawable area--the (w,h) that you
|
||||||
|
* specified when you created the window--and the coordinates
|
||||||
|
* of the upper left hand corner of the drawable
|
||||||
|
* area--which is NOT the (x,y) you specified.
