Feaure: support for changelogs

[GoogleCodeExporter]

It would be useful if Gource shows current version in addition to timestamp.

There could be couple of default place to choose where to find it:
*configure.ac (if project is using autotools)
*debian/changelog (if handling own debian-packaging)
*tags on version control system (if used in every release. 
http://code.google.com/p/gource/issues/detail?id=56 )

This can be also handled with same way how custom.log is handled, but log is 
not containing modifications but text:

1275543595|Version 0.1
1275545595|Version 0.2
1275583595|Version 1.0

Then users can make own spells (=scripts) how to rip own changelogs to this 
format.

I was about to file similar feature request, fortunately I found this one.

I'd like to share my view on how changelogs could be displayed: initially a 
change comment would appear in one of the corners (I'd choose bottom right). It 
would last for some time (based on the comment's length) and if there was 
another one to appear, it would pop out just above the previous one. If there 
were too many comments to display at one time, the oldest ones would disappear 
one by one, at the rate needed to make space for new comments so that there 
would be no delay.

I've done a bit of work on this feature:

http://github.com/acaudwell/Gource/commit/9ca60496552c371b0f24f1dc768851f2d15374
7c

As seen in this video:

I've only so far implemented the 'custom.log' style approach.

Right now it does get a bit hard to follow if a lot of events happen, so the 
representation still needs some work. Perhaps something similar to the second 
comments approach.

Cheers

Andrew

Is this feature implemented yet? because i can't get any comments into my 
animation via additional customlog parameters..?

but am i able to use it like in the video you posted with version 0.4?

(btw. i did a php script to convert SVN logs into CusomLogs with path copy 
support, because somehow the direct SVNlog feed didn't show copied paths. Would 
you like me to share it somehow with you?)

Hi.

I have just rebased this work on top of 0.4 (on the branch captions-rebase 
currently):

https://github.com/acaudwell/Gource/commit/596638034fa4eacbcd6c2aeee3f2dee7b4146
b5e

(see gource -H for the command line options for captions):

I have done some work in the past on the SVN copy command support, it just 
hasn't made it out there yet (I got distracted trying to animate directory/file 
renames).

Cheers

Andrew

Sorry to interrupt you once more but with this commit the 
captions.cpp/captions.h files are missing and if i use the old once from two 
years ago the make complains that "vec2f" and "vec3f" are no types (and some 
other stuff).

Thanks for all the great response!!
