ANNOUNCEMENT: MathMap 1.3.2

[mark....@gmail.com]

Dear MathMap users,

I'm happy to announce the release of MathMap 1.3.2, which offers the
following new features:

* Compositions can be saved and used as parts of other compositions.
* Colors, gradients and curves can be passed to filters, which now
makes all filters usable in the composer.
* More filters for use in the composer (including almost all GIMP
layer modes).
* Optional multi-threaded final rendering (compile-time option).
* Bugfixes.

You can download it from the MathMap homepage or from one of the links
below.

The MathMap homepage can be found at

Binaries for several Linux distributions are available here:

Hi Mark,

Thanks, this is working great ... but something seems weird with the C
generator on my fractal expressions. I haven't noticed the size of the
C files in a long time, so I am not sure how long this has been true.
The attached mm file, 102 lines long, turn into a C file of over 34190
lines, mostly composed of tmp_####_# = tmp_####_# lines. I've also
attached that. Any ideas??? :)

Tom

Thanks for this report! It turns out this was a bug in the dead code
elimination that led to dead code in loops being left over which
multiplied with your nested loops. It's fixed in public Hg - the code
produced for your filter now shrinks to about one third of its size.
It doesn't run any faster, though, because GCC eliminates the dead
code anyway.
