Circle functions operate on diameter instead of radius

[John Westhoff]

All of the circle functions for modifying terrain in World.java have a parameter r or R that act as a diameter and not radius. For example:

Lines 544 to 569 in 141569f

         /** 
          * Clears a circle using the standard square method 
          * 
          * @param X - X coordinate of the circle's center 
          * @param Y - Y coordinate of the circle's center 
          * @param R - Radius of the circle 
          */ 
         public void ClearCircle(int X, int Y, int R) { 
             // long time = System.nanoTime(); 
             for (int i1 = Math.max(X - (R + 1), 0); i1 < Math.min(X + (R + 1), w); i1++) { 
                 for (int i2 = Math.max(Y - (R + 1), 0); i2 < Math.min(Y + (R + 1), h); i2++) { 
                     if (Math.pow(i1 - X, 2) + Math.pow(i2 - Y, 2) < Math.pow((R / 2), 2)) { 
                         if (cellData[i1][i2] == OIL) { 
                             if (random.nextInt(10) == 2) { 
                                 cellData[i1][i2] = AIR; 
                                 // oilExplode(i1, i2); 
                                 entityList.add(new ExplosionEntity(i1, i2, 8, 1)); 
                                 ClearCircle(i1, i2, 10); 
                             } 
                         } // if (cellData[i1][i2]!=STONE) 
                         if (cellData[i1][i2] != CRYSTAL && cellData[i1][i2] != ETHER) { 
                             cellData[i1][i2] = AIR; 
                         } 
                     } 
                 } 
             } 

R here is treated as a diameter. These functions should carefully be changed to actually treat R/r as a radius, as well as have their calls changed accordingly.
