In order to use pbo's efficiently, the transfer operation has to
be separated from the use of the downloaded data which requires some
rearchitecturing around glcolorconvert/gldownload and elements
Depending on the platform, it was only ever implemented to 1) set a
default surface size, 2) resize based on the video frame or 3) nothing.
Instead, provide a set_preferred_size () that elements/applications
can use to request a certain size which may be ignored for
videooverlay/other cases.
Removes the use of NSOpenGL* variety and functions. Any Cocoa
specific functions that took/returned a NSOpenGL* object now
take/return the CGL equivalents.
The hack causes deadlocks and other interesting problems and it really
can only be fixed properly inside GLib. We will include a patch for
GLib in our builds for now that handles this, and hopefully at some
point GLib will also merge a proper solution.
A proper solution would first require to refactor the polling in
GMainContext to only provide a single fd, e.g. via epoll/kqueue
or a thread like the one added by our patch. Then this single
fd could be retrieved from the GMainContext and directly integrated
into a NSRunLoop.

Soon after setting two variables to 1, the code checks if their values are
different from each other. This would never be true. Removing this.

Actually we should always recalculate buffer size since our buffer size
even when not-padded is smaller for many sub-sampled formats. This is
because we don't add padding between the planes.

Problem was that if buffer was mapped READWRITE (state of buffers from
libav right now), mapping it READ/GL will not upload. This is because the
flag is only set when the buffer is unmapped. We can fix this by setting
the flags in map. This result in already mapped buffer that get mapped
to be read in GL will be uploaded. The problem is that if the write
mapper makes modification afterward, the modification will never get
uploaded.

A context can create a GLsync object that can be waited on in order
to ensure that GL resources created in one context are able to be
used in another shared context without any chance of reading invalid
data.
This meta would be placed on buffers that are known to cross from
one context to another. The receiving element would then wait
on the sync object to ensure that the data to be used is complete.
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.
Otherwise interesting things will happen in Cocoa applications, like
infinite event loops that block the NSApplication loop forever.
This was only needed for GNUStep and thus can safely be removed now.
Until gcc and GNUStep properly support Objective-C blocks and other
"new" features of Objective-C we can't properly support them without
making the code much more ugly.

It's architecture dependent and should not be placed into the include
directory as the assumption is that all those headers are architecture
independent.

Otherwise when resizing the window you will also get messages like:
class NSConcreteMapTable autoreleased with no pool in place - just leaking
class NSConcreteValue autoreleased with no pool in place - just leaking
class NSConcreteValue autoreleased with no pool in place - just leaking
class __NSCFDictionary autoreleased with no pool in place - just leaking
Need to set the ':' as the reshape method now takes one parameter.
For the story, the GstGLNSView was previously inheriting from
NSOpenGLView which has a reshape function without any parameter.
Now the GstGLNSView inherits from NSView and we re-use the reshape
function manually.
Use the reshape function after being defined. The other way
would have been to declare the reshape function in the header.

GTK-Doc uses a special syntax for code documentation. A multiline comment that
starts with an additional '*' marks a documentation block that will be processed
by the GTK-Doc tools. So GTK-Doc is confused if a comment block starts with that
additional '*' but isn't meant to be processed. Removing this additional '*'.
