Detailed Description

Vulkan SDL_ttf text renderer.

VKText rasterises text strings into SDL surfaces, uploads them as Vulkan image textures, and batches the resulting quads for submission during the render pass. Each printTextG_Solid() call adds one TextQuad to the pending queue, which is flushed by renderText().
