Unfortunately on further testing with GLM 0.9.9 (which is in alpha) it was
found to be unstable due to a change to the library removing default
constructors of vectors, resulting in uninitialized values being used.

The current release of GLM 0.9.8 is fine.

…ved).

The current GLM 0.9.9 pre-release alpha contains a change removing the
default initialization of vectors with no way of getting the old behavior.

This issue is compounded by Debian (and now Ubuntu) packaging this version of
GLM despite it being an alpha and not backwards compatible. I expect a lot of
other software will be affected by this decision as well.

For the time being I have decided to use a fixed version of GLM 0.9.8.5 including
a fix to compile with minor versions of GCC >= 7.3 which has not been included in
an official release yet.

Add src/core/glm to tarball.

This is significant for tools like doclifter that lift to XML/HTML.

After the first commit in a log is read to check the file format the log
it is rewound to the beginning, however the last line read was still buffered
so it would return the buffered line next not the first line of the log. As
custom log entries are all on one line this would erroneously be parsed as the
first commit.

Enabling this option causes gource to use the time of the
parent commit, if the time of a commit is in the past.
This allows a linear simulation, even if the time of the
commits are not corresponding to the order of the commits.

When the commit queue is empty lasttime use lasttime instead of currtime
to determine if the commit time is out of order as currtime is incremented
by the simulation.

Using this option allows to move the directory
name to the root (0.0) or to the leafs (1.0).

Renamed midpoint to label_pos.

Enabling this option causes gource to use the filename
as the file extension if no extension is set or the
filename ends with a dot. As a result every file without
an extension has an own entry in the file extension key.

…lection.

While parsing a commit when the parser encountered the first line
of the next commit it would buffer it to be parsed next, however
it didn't use the correct method to then fetch the next line so the
buffered entry was missed.

…tamp.

Thanks to Lars Schmertmann for helping debug this issue.
