b006ef97fc gluploadelement: try to avoid dropping buffers
Without this, a buffer is dropped if glupload indicates that it is
necessary to reconfigure.
Avoid this by explicitly reconfiguring immediately and uploading the buffer
again.

6e591403a7 glimagesink: make multiview none equivalent to mono
Fixes the internal viewconvert to not scale buffers for output with the
following pipeline:

gltestsrc ! glimagesink

It also fixes overlay composition with a resized output with an OpenGL
upstream:

gltestsrc ! timeoverlay ! glimagesink

57f07fcbd4 glimagesink: only update the output info iff there's a valid display_rect
Attempting to use the MAX(1, display_rect) would result in the overlay
composition attempting to draw into 1x1 buffer and calculate some
grossly incorrect sizes.

previously failing case:

55ec47f555 vorbisdec: Initialize decoder directly once we have the 3 headers

Also drop non-identification headers arriving after initialization or

they would just accumulate.

e05e8117e7 opusenc: fix segmentation fault at x86 version
The argument 0x0 is interpreted by the x86 compiler as a 32-bit int, but
it is consumed as a 64-bit uint causing a segmentation fault. We need to
explicit cast it to guint64 in order for the va_list to be built correctly.

41b7a65b81 meson: Add an option for the 'Tremor' Vorbis implementation
It makes sense to control it explicitly to allow us to enable it on
platforms that don't have hardware floating-point, and to allow people
to enable the 'vorbis' plugin without having to also provide the
Tremor dependency which is useless on most devices.

0619168e2a vorbisdec: Always handle in-band header packets once the first non-header packet arrives
And clean up any old pending headers if we receive a new identification
header, or if we receive a new set of headers via caps.

Otherwise it might happen that we receive one or more header but not
all, and then afterwards all headers again, and libvorbis does not like
getting headers passed multiple times and would error out.

It only makes sense to pass the very latest headers to the decoder at
the time we can actually make use of them.

2ace14f613 pango: Create one context per instance and remove class mutex
PangoCairo is thread-safe as long as the context and fontmap are not
shared between threads. Previously each subclass had its own context and
a class mutex for this reason, but apart from hurting performance this
was also not completely safe yet: the same fontmap might've been used by
different classes from different threads as the thread-default fontmap
(at time of class initialization) was used.

e4bf9ed8f0 gl/utils: Fix NDC conversion matrices for column-majorness
The matrices were converting the wrong values with non-diagonal-only matrices.
e.g. a typical yflip matrix in [-1,1]^3 such as
 1  0  0  0
 0 -1  0  0
 0  0  1  0
 0  0  0  1

Would have actually required a matrix like this in [0,1]^3
 1  0  0  0
 0 -1  0  0
 0  0  1  0
 0 -2  0  1

Which is
1. not consistent with our multiplication convention and would require
   transposing matrices or changing our multiplication order (from what is
   generally used on opengl matrix guides/tutorials).
2. Produces incorrect values when input with actual vertices accounting for
   the difference in multiplication order.  e.g. some vertices multiplied by
   the yflip matrix using vertex * yflip(== transpose(yflip) * vertex):

     vertex:       -> result:           expected:
     vec4(1,0,1,1) -> vec4(1,-2,1,1)    vec4(1,1,1,1)
     vec4(1,1,1,1) -> vec4(1,-3,1,1)    vec4(1,0,1,1)

With the updated values, we now get the expected values.

Includes a test for this behaviour and the example above

567bbe3c07 glcolorbalance: Support OES textures for input/passthrough
glcolorbalance is in the default GL path inside glimagesink,
so has been causing an possibly-unnecessary extra texture copy
on Android for a while now. If we're just doing passthrough,
we can support OES directly. If not, they'll be transformed
to 2D textures and colourbalanced.
