Synopsis
status, r, g, b, a = cpattern:GetCornerColorRGBA(patch_num, corner_num)
Function
Gets the color information in corner corner_num of patch patch_num for a mesh pattern.

patch_num can range from 0 to n-1 where n is the number returned by cpattern:GetPatchCount().

Valid values for corner_num are from 0 to 3 and identify the corners as explained in cairo.PatternMesh().
