more efficient (faster and has less overhead) than marshalling everything to the

Revert "glpool: fix caps refcount issue"
This reverts commit
3bdcdedfa00b87f1db505218789178318a16c743.
gst_caps_replace() takes a new reference already, if there is a problem then
it is elsewhere. And there are a few problems, see

glquery: provide compat definition for GL_QUERY_RESULT
e.g. android doesn't have it
While we're here move a state specific assertion after the supported check.
Removes an assertion on GLES

gl: add compatibility definition of GLint64
e.g. anrdoid doesn't have it

glpool: fix caps refcount issue
The caps are from an allocation query which are transfer none but were being
treated as transfer full.

gl: add a gstglquery object for arbitrary GL queries
Currently only GL_TIME_ELAPSED and GL_TIMESTAMP are supported

gldebug: implement a delayed debug system
The messages are stored by gst_gl_async_debug_store_log_msg() and output later
by a corresponding store(), output() or an unset()/free().
Some wrapper macros are provided to avoid callers explicitly using __FILE__,
GST_FUNCTION and __LINE__

gldebug: use gst_info_vasprintf in insert_debug_marker()
Allows expansion of GST_PTR_FORMAT and GST_SEGMENT_FORMAT arguments.

gl: add a videoflip element
Behaves exactly the same as the non-GL videoflip element

glfilter: recreate the fbo on caps changes
The width/height may change which requires recreating the depth buffer.

glbasefilter: add a class function on set_caps (from GL)
This is simply a convenience to avoid duplicating the thread marshalling on
set_caps.

gltransformation: always build a valid mvp matrix
The default case is to build an identity matrix.

gltransformation: support negative scales
A scale of -1.0 means to flip the video.

gltransformation: implement navigation events
Reverses the transformation applied through the properties and forwards the
event.
The process for finding the coordinates on the video are as follows:
1. Convert the given pointer_x and pointer_y to model space at the near and far planes
2. Get the equation of the video plane
3. Find where the ray in 1 intersects the plane
4. Profit!

Otherwise we won't get the button press events and GstNavigation fails.

glcolorconvert: try harder to passthrough
This makes a pipeline like:
... ! video/x-raw(memory:GLMemory),format=UYVY ! glcolorconvert !
video/x-raw(memory:GLMemory),format={UYVY, NV12} ! ...
passthrough instead of converting UYVY => NV12. The conversion would happen
before this change since the element (and basetransform) transform the src caps
to format={NV12, UYVY} (since NV12 comes first in the glcolorconvert:src
template) and then the default caps fixate func would fixate to NV12. Blah.
Also there's no need to intersect against the template caps in ::transform_caps
since basetransform does that right after calling the vfunc.

gl: implement a colorbalance element
It performs the exact same operation as videobalance but with opengl shaders and
was tested with glvideomixer by comparing frames from videobalance and
glcolorbalance.
