E17 with GL

Question

Here's a PKGBUILD and patch I put together that'll build an e-CVS package that has Evas using it's OpenGL engine. It's nothing fancy, more info can be found here but it works quite well with my nvidia card. I'm writing this with the layered sky background running at full steam behind Firefox. The E17 modules support the transparency but Eterm doesn't at this stage and I don't know if it will but this isn't meant for full-time use, just to have a squiz.
For it to work, I use nickm's packages and it only requires a rebuild of e-CVS. Also, you'll need to delete (or move) ~/.e/e/config/e.cfg as it tells Evas to use software and if you change the theme it resets that file and after a restart it's back to software as well. This is just for playing but it's not too shabby at all

Hi!
Thanks for taking the time to look at it, here are the news, (it is really nothing special, but one doesn't have to remove e.cfg )
There's also some news regarding OpenGL mode. First of all if you haven't read about it yet, please read me previous newspost first. As as I said in the earlier post, one major problem with it was that the engine settings weren't being saved to e.cfg, so every time you restarted E, everything went back to software mode. This has been solved by Korda (he also posted the original instructions on enabling GL mode). This is just copypasted from the edevelop.org forums - this has been written by Korda:
"OK, I've figured out why the config changes weren't sticking.
There are a few lines missing in e_config.c which cause all the evas_engine_* variables to never be saved when e.cfg is written.
Inside e_config.c in the e_config_init(void) method, you'll need to add the lines:
Code:
E_CONFIG_VAL(D, T, evas_engine_default, INT);
E_CONFIG_VAL(D, T, evas_engine_container, INT);
E_CONFIG_VAL(D, T, evas_engine_init, INT);
E_CONFIG_VAL(D, T, evas_engine_menus, INT);
E_CONFIG_VAL(D, T, evas_engine_borders, INT);
E_CONFIG_VAL(D, T, evas_engine_errors, INT);
E_CONFIG_VAL(D, T, evas_engine_popups, INT);
E_CONFIG_VAL(D, T, evas_engine_drag, INT);
after all the other similar lines but before the line
Code:
e_config = e_config_domain_load("e", _e_config_edd);
This ensures that all the evas_engine_* config variables get written.
