[XaraXtreme-dev] Just checked in...

[Phil Martin <phil@xxxxxxxx>]

I've just checked in changes to allow the conditional code enabled by 
DO_EXPORT to compile.

This gives the program the ability to save XAR files for the first time 
but this is still in its early stages and some crucial things don't 
work, for instance you can't save any doc that contains a bitmap at the 
moment.

* All use of EPS filters and EPS render regions is disabled and marked 
with PORTNOTEs.
* All use of the Bitmap preview dialog is disabled and marked with 
PORTNOTEs.
* The GIF filter is in but does nothing because we don't yet have a GIF 
reading/writing library in the code. Did the GIF patent lapse recently? 
Can we use giflib now?
* Use of the old Microsoft TRY CATCH END_CATCH macros has been replaced 
by C++ try and catch constructs. The catch handlers in bitmap filters 
catch all exceptions at the moment since the original CFileExceptions 
don't exist in LX. Maybe this should be tighted up.
* Tweaked svnversion.h generation and placed it inside cversion.h so 
that correct version information is written out into XAR files when they 
are saved.
* Re-enabled lots of palette optimsation code (untested).
* jpeg library is included more consistently using the same namespace 
throughout to avoid clashes with other "JPEG" symbols
* JPEGErrorManager now contains a jpeg_error_mgr instance rather than 
being derived from it

I have defined an enum containing bitmap filter IDs that originated from 
Accusoft and/or Snowbound commercial libraries. Hope it's OK to bring 
that info across into LX.

Some of the re-enabled code needs to be moved from the Oil layer into 
the Kernel, but to keep this checkin simple I will do that later.

You must use "make clean" before you build these changes because of 
dependency changes around svnversion.h (and obviously autoreconf and 
configure).
