Promote the libjpegturbo module to extension status
Choose one of: Under Discussion, In Progress, Completed, Rejected, Deferred
libjpegturbo is a native library accelerating the JPEG encoding by a factor of 2-5 compared to the standard JPEG lib.
The speedup is particularly signicant on Windows 64 bits and whenever the ImageIO native extensions are not available, as the JPEG library installed in the JDK is slower than the one provided by ImageIO native extensions (and libturbojpeg is faster than both).
A system using PNGJ as the PNG encoder, and libturbojpeg as the JPEG one, can effectively run at top performance without having to install the ImageIO native extensions at all (the JAI native extensions are still required to accelerate image processing operations such as rescaling or reprojection though).
Move the libjpegturbo 2.0 module to extension status.
The module has a handful of users (at least 3): yes, the module is in use by the municipalities or Firenze and Bolzano, and DLR
This section should contain feedback provided by PSC members who may have a problem with the proposal.
No backwards compatibility issues should arise.
