v3.2.2

• Fixed inability to upscale by pixels.
• Fixed an error in response to requests for images less than 3 pixels on a side when sharpening is enabled, in all processors using the Java 2D pipeline.
• Fixed an error in JaiProcessor when attempting to scale an image less than 3 pixels on the smallest side.
• Fixed a bug in FilesystemCache that caused zero-byte files to be written and an HTTP 500 response when handling concurrent identical requests.
• Error responses include a more appropriate Cache-Control header rather than the one set in the configuration.
• Trailing slashes in X-Forwarded-Path header values are trimmed off, preventing double-slashes from appearing in generated URLs.
