-====== SetCursorArea ======
-{{tag>cursor}}
-''void SetCursorArea(fixed width, fixed height)''
-===== Description =====
-Sets the size of the cursor coordinate system. The coordinate system used by the cursor matches the [[zdoom>SetHudSize]] coordinate system exactly.
-Cursor position is fully fixed-point, even ''SetCursorArea(1.0, 1.0)'' will work correctly.
-When this function is called, cursor position is changed so that the cursor remains in the same place on screen after coordinate system change.
-The default size is 640x480 (''SetCursorArea(640.0, 480.0)'').
-<note tip>Use the same coordinate system for both the cursor and the hud, like this:
-<code>
-SetCursorArea(640.0, 480.0);
-SetHudSize(640, 480, 0);
-</code>
-Or, using [[:HudLib]]:
-<code>
-SetCursorArea(640.0, 480.0);
-HudSetVirtualSize(640.0, 480.0);
-</code>
-</note>
-===== Examples =====
-<code>
-// The cursor is in the center of the screen.
-SetCursorArea(640.0, 480.0);
-CursorX() -> 320.0
-SetCursorArea(320.0, 240.0);
-CursorX() -> 160.0
-SetCursorArea(1.0, 1.0);
-CursorX() -> 0.5
-</code>
