1a613c5d4e gl: shadervariables: make parsing of floats locale-independent
Floating point numbers are written differently in different
locales, e.g. in many countries 1/2 = 0,5 instead of 0.5, and
strtod will not be able to parse "0.5" correctly in such a
locale.

a31faecb8b aggregator: Block serialized events/queries until the pad has consumed all buffers
Otherwise the caps of the pad might change while the subclass still works with
a buffer of the old caps, assuming the the current pad caps apply to that
buffer. Which then leads to crashes and other nice effects.

3637296ee9 videoaggregator: Do not to release VIDEO_AGGREGATOR_LOCK while setting format info
We should be able to always keep the VIDEO_AGGREGATOR_LOCK while
negotiating caps, this patch introduce that change.

That also implies that we do not need the SETCAPS_LOCK anymore because
now VIDEO_AGGREGATOR_LOCK guarantees that setcaps is not called from
several threads and the gst_aggregator_set_caps method is now
protected.

1b4547ff93 aggregator: Take lock to ensure set_caps is not called concurently
Avoiding to be in an inconsistent state where we do not have
actual negotiate caps set as srccaps and leading to point where we
try to unref ->srccaps when they have already been set to NULL.

f2af838837 videoaggregator: Revert the last commit and handle resolutions differences properly
This is about converting the format, not about converting any widths and
heights. Subclasses are expected to handler different resolutions themselves,
like the videomixers already do properly.

Leads to ugly assertions instead of properly erroring out:
CRITICAL **: gst_video_converter_new: assertion 'in_info->width == out_info->width' failed

c4cc2dfabf gl/cocoa: Always update our viewport if Cocoa tells us something has changed
The visible rect and bounds might be the same as before, but Cocoa
might've changed our viewport without us nothing. This happens if
you hide the view and show it again.

Don't update the screen until we redraw, this prevents flickering during
scrolling, clipping, resizing, etc

it is in and clobber that one instead.
