Rounded rect not clip correctly with FICImageFormatStyle8BitGrayscale

[wongzigii]

Currently, I found that the thumbnail image with FICImageFormatStyle8BitGrayscale are not clipped correctly. The default color one is FICImageFormatStyle32BitBGRA. However, the gray one is not rounded rect, as we hoped for.

Here is how the drawingBlockForImage looks like:

- (FICEntityImageDrawingBlock)drawingBlockForImage:(UIImage *)image withFormatName:(NSString *)formatName {
    FICEntityImageDrawingBlock drawingBlock = ^(CGContextRef context, CGSize contextSize) {
        CGRect contextBounds = CGRectZero;
        contextBounds.size = contextSize;
        CGContextClearRect(context, contextBounds);

        // Clip to a rounded rect
        CGPathRef path = _FICDCreateRoundedRectPath(contextBounds, contextSize.width/2);
        CGContextAddPath(context, path);
        CGContextClip(context);

        UIGraphicsPushContext(context);
        [image drawInRect:contextBounds];
        UIGraphicsPopContext();
    };
    return drawingBlock;
}
