fteqw/engine/shaders/vulkan/defaultwarp.glsl
Spoike b7784f41d9 Fix potentially serious vulkan performance issue.
Stripped obsolete vk_nv_dedicated_allocation extension.
Misc fixes for warnings.
Linux now defaults to using ~/.local/share/fte instead of ~/.fte for greater consistency.
Other misc linux tweaks.
