* Fix regression caused by r4841. That patch assumed that JPEG encoding ↵DRC2012-02-133-45/+47

Reorganise and clean up the code to handle this, and make the raw frame buffer pointer const so that we might avoid such bugs in the future. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4841 3789f03b-4d11-0410-bbf8-ca57d06f2519

* Changing the deferred update timer to 10 ms caused a large performance ↵DRC2011-12-221-1/+1
| | | | | | regression on video/3D apps, and until we can quantify the benefits of a larger DUT value, it was decided that it should be changed back to 1 ms for the 1.2 release. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4825 3789f03b-4d11-0410-bbf8-ca57d06f2519
* We need to explicitly trigger a framebuffer update for server side renderedPierre Ossman2011-12-211-1/+3

* Increase the default compression level to cater to a broader range of usersPierre Ossman2011-11-202-2/+3
| | | | | | | | (bandwidth is often the limiting factor, rather than CPU). Further increases give little returns, so 2 is currently deemed the best tradeoff. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4811 3789f03b-4d11-0410-bbf8-ca57d06f2519
* The block size for the comparing update tracker was inefficently low. RaisingPierre Ossman2011-11-201-1/+1
