[vlc-devel] [PATCH 00/16] opengl: Abstract picture storage from renderer (part 1)

[Romain Vimont]

I initially posted a big patchset:
<https://mailman.videolan.org/pipermail/vlc-devel/2020-February/131046.html>

I will now post commits from my branch in smaller patchsets, easier to review.

Here is the first part of an updated version, which mainly fixes macOS and
Windows versions.

The significant changes in this patchset concern the way the picture
coordinates are converted to texture coordinates (patch 9) and the way the
stereo mode is computed (patch 12).

Here is a branch:

    https://code.videolan.org/rom1v/vlc/commits/glsampler-part1

And a "merge request" (into my own fork) with CI:
