The unconditional Y-flip is needed for Vulkan 1.0 since D3D12 and Vulkan coordinate systems differ. Conditional YZ-flip is needed if we want to support negative viewport height/depth. Prepare spirv_to_dxil() to support that, and while at it, prepare things for multi-viewport: the Y/Z flips are per-viewport and encoded in a 32bit bitmask, with the upper 16bits reserved for Z flips, and the lower 16bits reserved for Y flips.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question.
