Matthias Clasen Continues Hacking On GTK4's Vulkan Support

Of the many improvements I am excited for with the GTK4 toolkit is the introduction of a Vulkan renderer.

As noted earlier this month, there's been an uptick in GTK4 Vulkan work and Red Hat's Matthias Clasen has continued in that theme through the end of the month.

Some of the recent work on GTK4's Vulkan support includes improving its glyph cache that was initially added earlier this month, warning/error handling improvements, blend modes support, a new API to create intermediate textures, adding semaphores to the command buffer submit API, support for multiple render passes, repeating sampler, and as of last night is also support for render nodes in Vulkan. This is on top of a variety of smaller improvements/fixes/changes.

The ongoing GTK4 Vulkan work can be browsed here. I wish there was a GtkPerf-like GTK4 benchmark for testing, but alas there is not at this point.
