Some backends may break as I only compiled SDL

byte depth.
2011-04-12COMMON: Replace MKID_BE by MKTAGMax Horn
MKID_BE relied on unspecified behavior of the C++ compiler, and as such was always a bit unsafe. The new MKTAG macro is slightly less elegant, but does no longer depend on the behavior of the compiler. Inspired by FFmpeg, which has an almost identical macro.

2011-02-06GRAPHICS: Improved JPEG decoder performanceBastien Bouclet
Replaced the 2D IDCT by two 1D IDCT (rows, then columns). JPEG images now decode about twice as fast as they used to. svn-id: r55794

2011-01-28GRAPHICS: Rename JPEG::_str to _streamMax Horn
We use _str to denote strings almost everywhere, so this was a bit confusing. Another alternative would be to use _s. svn-id: r55585

2010-09-18JANITORIAL: Removed most punctuation at end of warning() and error()Torbjörn Andersson

2009-12-31Worked around what appears to be a bad JPEG image in the Masterpiece edition ofTorbjörn Andersson
Myst. If I dump the image to file, I'm able to read it into other programs, such as The GIMP, just fine. It seems that the only thing that's missing is the End Of Image marker, and what everyone else does is to just fake one. svn-id: r46795
