[PATCH qemu-server/pve-manager/docs v4 0/1] add virtio-vga-gl OpenGL 4.6 & Vulkan (venus) support

[Markus Frank <m.frank@proxmox.com>]

v4:
* added docs patch
* pve-manager: change the memory label to '2D Memory Limit' when using
  VirtIO to make the difference to the 'Host Memory Window' clearer
* qemu-server: made the description of virgl-features more general

v3:
ran `make tidy` in both repos and applied the changes

v2:
The QEMU documentation got updated and now explains that adding blob and
hostmem alone with or without "venus=on" enabled support for OpenGL 4.6.
So I decided to let the user decide which "feature set" to use:
* the default with up to OpenGL 4.3 support
* OpenGL 4.6 (hostmem=<size>G,blob=true)
* Vulkan & OpenGL 4.6 (hostmem=<size>G,blob=true,venus=true)

There is also a patch on the qemu-devel list which separates Vulkan from
OpenGL.
https://lists.gnu.org/archive/html/qemu-devel/2026-03/msg05502.html
So in the future we could add a "vulkan without opengl" or "drm" option.

The hostmem option allocates a host memory region that acts as virtual
VRAM, enabling virglrenderer to map graphics 'blobs' directly to fixed
memory addresses.
