[ANeff] Bug for: image functions fail on png w/ .jpg extensionExamples:1) When a .jpg is renamed to .png, then isImageFile() returns true.2) When a .png is renamed to .jpg, then isImageFile() returns false.Another example: imageRead(PNG.jpg) throws error: "ColdFusion was unable to create an image from the specified source file.  Ensure that the file is a valid image file."This can be problematic, when working w/ a png that someone has renamed from .png to .jpg.

<!--- isImageFile(JPG.png) returns YES ---><cfscript>  myJPG = imageNew("", 10, 10, "grayscale", "black");  imageWrite(myJPG, expandPath("./myimage.jpg"), 1, true);  fileMove(expandPath('./myimage.jpg'), expandPath('./myimage.png'));  writeOutput(isImageFile(expandPath("./myimage.png")));//result "YES" (good)</cfscript><!--- isImageFile(PNG.jpg) returns NO (bug?) ---><cfscript>  myPNG = imageNew("", 10, 10, "grayscale", "black");  imageWrite(myPNG, expandPath("./myimage.png"), 1, true);  fileMove(expandPath('./myimage.png'), expandPath('./myimage.jpg'));  writeOutput(isImageFile(expandPath("./myimage.jpg")));//result "NO" (bug?)</cfscript>
