+/**
+ * Class that represents a grid of patches. Adjacent patches share their corners and a color is 
+ * specified at each one of them. The colors are bilinearly interpolated across the patch.
+ *
+ * This implementation defines a bidimensional array of patches. There are 3 arrays to store the 
+ * control points of the patches to avoid storing repeated data since there are several points
+ * shared between adjacent patches. 
+ *
+ * The array fCornerPts stores the corner control points of the patches.
+ * The array fHrzPts holds the intermidiate control points of the top and bottom curves of a patch.
+ * The array fVrtPts holds the intermidiate control points of the left and right curves of a patch.
+ * The array fCornerColors holds the corner colors in the same format as fCornerPts.
+ * The array fTexCoords holds the texture coordinates in the same format as fCornerpts.
+ *
+ *               fCornerPts               fHrzPts                  fVrtPts
+ *             --------------       -------------------         --------------
+ *            | C0 | C1 | C2 |     | H0 | H1 | H2 | H3 |       | V0 | V1 | V2 |
+ *             --------------       ------------------         ---------------

+ * With the above configuration we would have a 2x2 grid of patches:
+ *               H0     H1 H2   H3
+ *              /        \/      \

+ *           v0 |        v1       | v2
+ *           v3 |        V4       | v5
+ *             \|        |        |/
+ *              C3-H4-H5-C4-H6-H7-C5
+ *             /|        |        |\

+ *               \      / \      /
+ *                H8   H9  H10  H11
+ *
+ * When trying to get a patch at a certain position it justs builds it with the corresponding 
+ * points.
+ * When adding a patch it tries to add the points at their corresponding position trying to comply
+ * with the adjacent points or overwriting them.
+ * 
+ * Based the idea on the SVG2 spec for mesh gradients in which a grid of patches is build as in the
+ * the following example:
+ * <meshGradient x="100" y="100">
+ *      <meshRow>
+ *          <meshPatch>
+ *              <stop .../>
+ *              Up to four stops in first patch. See details below.
+ *          </meshPatch>
+ *          <meshPatch>
+ *              Any number of meshPatches in row.
+ *          </meshPatch>
+ *      </meshRow>
+ *      <meshRow>
+ *          Any number of meshRows, each with the same number of meshPatches as in the first row.
+ *      </meshRow>
+ * </meshGradient>
