class Texture : public portal::renderer::RendererResource

Abstract texture interface with mipmap, sampler, and cube texture support.

Wraps Image with texture-specific functionality: mipmap queries, sampler configuration, predefined texture IDs (missing/white/black), and texture type (2D/cube). Supports CPU buffer access and resizing.

Subclassed by portal::renderer::vulkan::VulkanTexture
