65c57b77ff gl: element buffers are part of vao state
Use them as such.  They are also required for GL3 core profile support
with glDrawElements on OS X.

3613ecfd0a glfilter: Remove onStart/onStop vfuncs, and unused onReset()
onStart/onStop are just duplicates of the basetransform ones, onReset
was never called but was used everywhere when stop should've been used.

2729949b39 gloverlay: Fix upside down and miss-aligned JPEG
LibJPEG uses macroblock of 8x8 sample. In this element we use RGB and
Y444, two 24bit formats that are stored in 32bit pixels. This mean we
have 32x32 bytes macroblocks. For this reason, we need to allocate
our buffer slightly larger. We also need to pass the line pointer in
the right order, otherwise the image endup upside-down.

certain platform when used with libav and no luck.
