cb9463d1a2 glbasefilter: add a class function on set_caps (from GL)
This is simply a convenience to avoid duplicating the thread marshalling on
set_caps.

1fe2996b01 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!

c2a6c97a1d 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.

It performs the exact same operation as videobalance but with opengl shaders and

86110c4765 glupload: always add texture-target field to GL caps
1. Various elements/base classes only perform a subset check on accept-caps
2. Some GL elements have texture-target in their pad template
3. When checking subsets, only the caps to check are allowed to contain extra
   fields.  If the 'template' caps have extra fields, the subset fails.
Thus without texture-target on the caps, various accept-caps implementations
were failing.

Also, add some convenience functions for setting and retrieving
texture targets to/from GValue.

633c26884e glmemorypbo: fix wrapping data on GL 2.1
GL 2.1 only supports pbo upload.

The wrapped data pointer was only being set on the pbo memory and on the
glmemory so when a download was requested (in GL 2.1), glmemory was
allocating a new data pointer and thus not returning the wrapped data.

1403a6871f glwindow: Hide navigation specific internal API and add API to asynchronously send navigation events
Exposing the navigation thread's main context, GSourceFuncs and structs called
key_event and mouse_event is exposing a bit too much of the internals. Let's
just go with two functions to asynchronously send navigation events on the
window with the same API as the synchronous ones.

8492c045a4 glupload: Add dmabuf upload method.
This upload method detect and optimize uploads of DMABuf memory. This is
done by creating and caching EGLImages wrapper around DMABuf. The
EGLImages are then binded to a texture which get converter using
standard shader.

Example pipeline:

GST_GL_PLATFORM=egl \
gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 ! \
               video/x-raw,format=NV12 ! glimagesink

0468dc6663 eglimagememory: Methods to create GstGLMemory from dmabufs
Maps GstVideoFormats to suitable DRM fourccs which work with
glcolorconvert, using gst_gl_memory_alloc(). We require mostly
only 4 formats to be supported by the driver. We require DRM
equivalent to RGB16, RGBA, R8 and RG88. This way it's compatible with
DesktopGL, since GL_TEXTURE_2D is used and limit driver requirements.
With this we can virtually support all formats the glcolorconvert
supports.
