b1fd1d34bd gl/effects: use non-PBO GLMemory for internal textures
middle textures in gleffects do not need to use GstGLMemoryPBO as they
aren't transfering data to/from the GPU. This will cost too much DMA
memory and cause performance issue. Change the allocator to use non-PBO
GstGLMemory.

5e3157098a glvideomixer: Reject multiview video
glvideomixer does not support it currently and it needs special support
for handling this correctly, and is rather non-trivial to implement for
all formats.

bb0a83b018 plugins: Use explicit type conversion from enums
MSVC warns about this because it's a C++ compiler, and this actually
results in useful things such as the incorrect 'gboolean' return value
for functions that return GstFlowReturn, so let's do explicit
conversions to reduce the noise and increase its efficacy.

f790863755 Explicitly define float constants as float
With MSVC, this gives the following warning:

warning C4305: 'function': truncation from 'double' to 'gfloat'

Apparently, MSVC does not figure out what type to use for constants
based on the assignment. This warning is very spammy, so let's try to
fix it.

1ffe22240a gluploadelement: fix leak of upload library object

_transform_caps() but will never be unreffed as the only case is in _stop().

78e91a731f glcolorbalance: reconfigure on passthrough changes
Fixes an assertion when moving from passthrough to non-passthrough

Without an explicit reconfigure, glfiter won't have created the GL
resources such as the FBO, GL bufferpool, etc and basetransform will
allocate sysmem buffers instead.

c16d57cc9a glupload: create the GstGLUpload object in ::transform_caps
Previously it was created in the init function and destroyed in ::stop, which
lead to segfaults when reusing the element.

Now the upload object is created in ::transform_caps if it is NULL, which is the
earliest we need it. The other vfuncs already bail out if the upload object is
NULL, which means that negotiation wasn't done.

91fea30ff4 gstglupload: make the GLMemoryUpload method output the correct texture-target
Now when used with video/x-raw as input, the GLMemoryUpload method checks for
->tex_target in input GLMemory(es) and sets the output texture-target
accordingly.

Fixes video corruption with a pipeline like avfvideosrc ! video/x-raw !
glimagesink where on macos avfvideosrc pushes RECTANGLE textures but glupload
was configuring texture-target=2D as output.

061a157ef5 glvideomixer: fix race retrieving the GL context from the display
_get_gl_context() can be called concurrently from either propose_allocation() or
decide_allocation().  If it so happens that this happens at the same time,
the check for whether we already had a GL context was outside the lock.  Inside
the lock and loop, the first thing that happens is that we unref the current GL
context (if valid) as if there was a conflict adding it to the display.  If the
timing was unlucky, subsequent use of the GL context would be referencing an
already unreffed GL context object resulting in a critical:

g_object_ref: assertion 'object->ref_count > 0' failed

fe7dd131f5 gltestsrc: fix shaders ref counting
The gltestsrc element uses two shaders: color_shader and snow_shader.
Those are alternatively assigned to the SrcShader->shader pointer and
their reference was transferred to it. Only the SrcShader->shader was
unreffed (in _src_shader_deinit()) so only one shader was properly
freed, the other one was leaked.

Fixed this by giving an extra ref to SrcShader->shader and unreffing the
2 shaders in _src_smpte_free().

7507b14dcd gltransformation: use the affine transformation meta if available downstream
We can avoid a render pass if downstream supports the affine transformation meta
and increase the performance of some pipelines involving gltransformation.

Implemented by checking for the affine transformation in the allocation query
from downstream and combining our matrix with that of upstream's (or creating
our own).
