Subject: [E-devel]  [Review] [Patch] Evas_GL bug fixes/updates

I've fixed some minor issues that I've been pushing off for later.

The patch does the following:

1. Evas_GL and Evas had an issue where the viewport parameters were
being reset in the wrong context. Previously, this issue was temporarily
patched by flushing evas' pipeline and setting
evas_gl_common_context_use(NULL) in EvasGL's
make current. I know, it was pretty hacky. It turns out that in
evas_engine,
there was a code evas_gl_common_context_resize(NULL) without doing
eng_window_use() first.  So i've added that part and problem went was
resolved properly. :-)

2. Naturally, I've taken out the temporary patch from 1.

3. I've added code that took care of glBindFramebuffer(..., fbo) where
the
fbo had to be saved and restored in case the user wanted to use his
own fbo.
Also, I've had to take care of the case when fbo is 0 since 0 need to
point
to evas_gl surface.

4. I've updated make_current a little as well.
