9f1cb84523 libgstgl: run a custom shader to convert YUV to RGB on mac and ios
When GL_APPLE_ycbcr_422 is available, run a custom shader to convert
GL_TEXTURE_RECTANGLE textures from YUV to RGB.

See https://www.opengl.org/registry/specs/APPLE/ycbcr_422.txt

966cad27d7 gl: initial support for texture targets other than GL_TEXTURE_2D
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.

API: modify GstGLMemory
API: modify gst_gl_memory_wrapped_texture
API: gst_gl_download_perform_with_data

f31ba88835 gstglcolorconvert: micro optimization
Don't call glClear && glClearColor at each draw since we're going to draw the
whole viewport anyway. Gets rid of a glFlush triggered by glClear on OSX.

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.

50a11e4a77 gl/cocoa: Disable hack for NSApp iteration with a special #define
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.

eeda7a29ce glbufferpool: Always recalculate buffer size
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.

45ac36ca26 glmemory: Handle upload/download flags from map
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.
