Bug in the drawIcon function

[ghost]

The out of range check in the drawIcon function is broken as this code illustrates. Using the current
version of drawIcon, the WiFi icon will not be drawn in the center of the lcd display because the range check fails. If the code is changed as shown in the header comment below drawIcon works as expected.

/*
 * This code should draw the WiFi Icon in the center of the display
 * But there is a bug in the function drawIcon
 * 
 * The line:
 * if ((x + iWidth) * scale >= _width || (y + iHeight) * scale >= _height) return;//cannot be
 *
 * Should probably be this line:
 * // if ((x + (iWidth * scale) >= _width) || (y + (iHeight * scale) >= _height)) return;//cannot be
 *
