6141d3fc7e glcolorconvert: add support for converting texture targets 
Solved with a simple shader templating mechanism and string replacements
of the necessary sampler types/texture accesses and texture coordinate
mangling for rectangular and external-oes textures.

681cb5b16d glmemory: add support for rectangle textures 
Add the various tokens/strings for the differnet texture types (2D, rect, oes)

Changes the GLmemory api to include the GstGLTextureTarget in all relevant
functions.

Update the relevant caps/templates for 2D only textures.

aa32408926 glcolorconvert: order the caps template so that RGBA is first 
glcolorconvert ! glcolorconvert would sometimes negotiated RGB
(the first list entry) otherwise.

6bb560a4eb glslstage: initialize output params to 0 before calling gl functions 
The client side API of the Chromium's GPU Process has asserts
in debug mode that check that output params are initialized to 0.

ad49a39e5b glcolorconvert: allow outputting multiple textures for gles3 contexts 
the USING_GLES2 includes all GLES3 contexts as well which does support
drawing to multiple buffers.  Instead make or decision solely based on
whether glDrawBuffers is available or not.

cfb0d7e9f3 glviewconvert: expose the element on gles2 platforms 
We can do everything with gles3 however gles2 restricts us not allowing
separated or frame-by-frame multiview modes due to multiple draw buffers.

c766ca0381 glshaderelement: implement setting arbitrary uniforms 
Currently float and int are supported by default. vec2, vec3, vec4
and mat4 are supported if graphene is used.  Of course if one wants
to set custom uniforms they can also be set using the create-shader
signal.

3a8fc708ee glshaderelement: implement on-demand create-shader signalling 
One may not have an GstGLContext available or current in the thread where one
would need to update the shader.  Support this by signalling create-shader
whenever the one-shot 'update-shader' is set to TRUE.

463e23bb47 glslstage: add brackets around pointer dereference referencing an array

moves/changes/etc.

def421acf6 gstreamer: bad: Fix memory leaks when context parse fails 
When g_option_context_parse fails, context and error variables are not getting free'd
which results in memory leaks. Free'ing the same.

And replacing g_error_free with g_clear_error, which checks if the error being passed
is not NULL and sets the variable to NULL on free'ing.

0580536fa1 glutils: use gst_element_set_context for setting display/other_context 
1. So we get tracking inside GstElement properly when e.g. adding to a bin
2. Removes redundant code.  Now only one place where
   GstContext->GstGLDisplay/GstGLContext transformation occurs
3. Fixes a memory leak in the process
4. Make the retrieval of debug categories thread safe

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.
