530ae2cbb0 glupload/download/convert: provide transform_caps functions 
Allows finer grain decisions about formats and features at each
stage of the pipeline.
Also provide propose_allocation for glupload besed on the supported
methods.

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.

the gst debug system.  Also fixes a segfault.

1c1084881b Revert "libgstgl: gstglcaopengllayer: set the layer as opaque" 
This reverts commit 6f152d381c.

The layer shouldn't be always opaque, it should be made a property.

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.

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.
