4bbda2b626 glframebuffer: rewrite for a more consistent API
Facilities are given to create fbo's and attach GL memory (renderbuffers
or textures).  It also keeps track of the renderable size for use with

ba00657e9d glviewconvert: fix transformation matrix usage

1153684a94 glmemory: add the texture type to allocate to parameters
Rather than assuming something.  e.g. zerocopy on iOS with GLES3 requires

This is also needed for zerocopy decoding on iOS with GLES 3.x.

db51c90d5d glcontext: correct precondition for get_gl_version

dfd6565b4b glsl: fixup external-oes shaders by mangling the required extension
Newer devices require using a different GLSL extension for accessing
external-oes textures in a shader using the texture() functions.

While the GL_OES_EGL_image_external_essl3 should supposedly be supported
on a any GLES3 android device, the extension was defined after a lot of the
older drivers were built so they will not know about it.  Thus there are two
possible interpretations of which of texture[2D]() should be supported for
external-oes textures.  Strict adherence to the GL_OES_EGL_image_external
extension spec which uses texture2D() or following GLES3's pattern, also
allowing texture() as a function for accessing external-oes textures

This adds another mangling pass to convert
 #extension GL_OES_EGL_image_external : ...
into
 #extension GL_OES_EGL_image_external_essl3 : ...
on GLES3 and when the GL_OES_EGL_image_external_essl3 extension is supported.

Only uses texture() when the GLES3 and the GL_OES_EGL_image_external_essl3
extension is supported for external-oes textures.
Uses GLES2 + texture2D() + GL_OES_EGL_image_external in all other external-oes
cases.

ecfe5b0801 gl: implement GstGLMemoryEGL
Because current GstEGLImageMemory does not inherit GstGLMemory, GLUpload
allocates additional GLMemory and upload the decoded contents from the decoder
which uses EGLImage (e.g. gst-omx in RPi).

This work adds GstGLMemoryEGL to avoid this overhead. Decoders allocate
GstGLMemoryEGL and decode its contents to the EGLImage of GstGLMemoryEGL.  And
GLUpload uses this memory without allocation of additional textures and blit
operations.

[Matthew Waters]: gst-indent the sources and fix a critical retreiving the egl
display from the memory.

85cddc0891 glcolorconvert: implement multiple render targets for GLES3
There are numerous slight differences required between Desktop GL and GLES3 for
multiple render targets.

1. gl_FragData doesn't exist at all and one is required to use
   'layout (location = ?) out ...' instead.
2. gl_FragColor doesn't exist, same as 1
3. texture2D() has been deprecated

Fortunately most of these have been taken care of with GL3 and the shader
mangling already exists so just expand the conditions they are used in.  The
gl_FragData issue requires a new mangle pass though.  We also use this new
pass on desktop GL for consistency.

90889bc73f libgstgl: cocoa, eagl: don't marshal GL calls to the context thread
Execute GL calls without marshalling them to the context thread. In the cocoa
and eagl backends calling gst_gl_context_activate is cheap and therefore calling
it on the current thread and serializing GL calls with a per-context lock is
more efficient (faster and has less overhead) than marshalling everything to the
context thread.

This optimization cuts a large overhead in g_poll (continuously waking up the
context thread) and in g_mutex_*/g_cond_* (waiting for results from the context
thread).

5f87cc0b65 glcontext: add a method to add a context to another share group
Intended for use with wrapped contexts that are created shared with gst's
gl contexts in order to manage the internal sharegroup state correctly.

e.g. with caopengllayer (which is used in glimagesink and caopengllayersink
on OS X), we create a CGL context from the gst context and the sharing state
was not being correctly set on either GL context and gst_gl_context_is_shared()
was always returning FALSE.

With 11fb4fff80 only flushing with multiple
shared contexts, the required flush was not occuring causing screen
corruption or stuttering.

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.

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.

93215927a9 glbasememory: add a generic interface for allocating GL memories

Every allocation would now go through gst_gl_base_memory_alloc with the
allocation parameters now being specified in a single struct to allow
extension by different allocators.

8f4ba29f97 gl: Allow using non-system mesa with both GL and GLES
GCC automatically disable redundance warnings for system headers. As
soon as we start using a non-system installed mesa, we would start
having issues. The test for both wasn't setting any flags, so it would
work but then fail at runtime.

This is being fixed by disabling in the code (where needed only) that
GCC warning. The test is also fixed to avoid the false positive we had.

63bbe9406a glwindow: add API to request a resize event on the next draw
- glimagesink needs to be able to resize the viewport on aspect ratio
  changes resulting from either caps changes or 3d output mode changes.
- Performing a glViewport outside the GstGLWindow::resize callback
  will not have the winsys' stack of viewports required to correctly
  place the output frame.

Provide a function to request a resize on the next draw event from the
winsys.

Also track size changes inside the base GstGLWindow class rather
than in each subclass.

78957c45c2 glcontext: track sharedness with a cookie
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree

Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!

This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.

6db457a7d9 gl: win32: do not call SetParent in release_parent_win_id()
When called from gst_gl_window_win32_close(), internal window
could not exist, and if it does it's going to be destroyed just
after that anyway. Also it causes window_proc() to be called
and crash because it gets a NULL context.

When called from gst_gl_window_win32_set_window_handle() we are
going to set another parent anyway, and it's probably better to
reparent directly instead of passing by a NULL parent which could
cause the internal window to popup briefly.

77e1e70fdc gl: win32: fix crash when finalizing GstGLContext
gst_gl_context_finalize() is calling gst_gl_window_win32_quit()
which was posting a message. But then window_proc takes window's
context and get a NULL.

Now that we've got a GMainLoop we can do like other backends and
simply call g_main_loop_quit().

This also remove duplicated code to release the parent window and
potential crash there because parent_proc could be NULL if we never
created the internal window. That could happen for example if setting
state to READY then setting a window_handle, and go back to NULL state.

x11 and wayland backends both create a custom GSource for this,
so there is no reason to not do that for win32.

0ad168a258 gl/cocoa: reduce custom main loop latency
This fix a very slow rendering rate regression that only
happens when using gst-launch, i.e. in the case where
the main thread does not run any NSApp loop.

Git bisect reported it has been introduced by the commit
e10d2417e2:
"move to CGL and CAOpenGLLayer for rendering".

Then the commit 7d46357627:
"gstglwindow_cocoa: fix slow render rate" attempted to fix
the slow rendering rate problem when using gst-launch.

At least for me it does not work. I tried several
combinations, for example to flush CA transactions in the
custom app loop, as mentioned in the doc, but the only solution
that fixes the slow rendering is by reducing the loop latency.
From what I tested, no need to put less than 60ms, even if the
framerate has an interval much lower (16.6ms for 60 fps).

0c459222f8 gstglwindow_cocoa: fix slow render rate
In gst_gl_window_cocoa_draw we used to just call setNeedsDisplay:YES. That was
creating an implicit CA transaction which was getting committed at the next
runloop iteration. Since we don't know how often the main runloop is running,
and when we run it implicitly (from gst_gl_window_cocoa_nsapp_iteration) we only
do so every 200ms, use an explicit CA transaction instead and commit it
immediately. CA transactions nest and debounce automatically so this will never
result in extra work.

Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

d8cc4cfc47 glmemory: use pbo's for download

019367c128 glwindow: remove width/height from _draw()
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.

It was missing the GstVideoAlignment padding which could cause GL
errors related to overrunning the size of the pbo.
