This was chosen over relying solely on the caps as glupload needs to propose an
allocation and set the texture target based on the output caps. Setting the
caps in the config is currently pointless as they are overwritten in a lot of
element's decide_allocation functions.
This provides a mechanism for the buffer pool to be configured for a certain
texture target when none has been configured.
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.
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.
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.
e.g:
gstglcontext_egl.c:613:7: error: implicit declaration of function 'strcmp'
[-Werror=implicit-function-declaration]
if (strcmp (G_MODULE_SUFFIX, "so") == 0)
While technically, i is always 0 and *vertex_sources[i++] is equivalant
to (*vertex_sources)[i++]. Be future-proof in the case of code
moves/changes/etc.

A GstGLShader is now simply a collection of stages that are
compiled and linked together into a program. The uniform/attribute
interface has remained the same.
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
These markers are visible in tools that record the GL function calls
such as apitrace, et al.
Makes it easier to match up GL draw commands with specific elements.
- 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.

when allocating memory. Fixes crashes with avdec_h265 in the AVX2
code path which requires 32-byte stride alignment, but the
GstAllocationParams only specified a 16-byte alignment.

HAVE_IOS is only defined for the build of this module so
attempting to use gstgl in iOS would result in incorrect GL
includes.
Use GST_GL_HAVE_PLATFORM_EAGL instead for choosing the iOS GL
header.
During allocation query, when this element is not passthrough, it must
relay the overlay compostion meta and it's parameters. Fortunatly, base
transform can do this for us.

GL_SHADING_LANGUAGE_VERSION was introduced since ES 2.0, but in some
android emulator doesn't support this feature. To prevent confusion for
developer, the error message need to be more clear.

Removes the redundant GL object creation/deletion on every
decide_allocation call which is being called for every caps change.
Thus reduces the required GL state changes on reconfigure events
which are being sent by glimagesink/xvimagesink
As we only expose the mapped portion of the frame into the GL
memory object (and not the original padding) we need to
re-calculate the size and offset.
