// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2026-09-07: Round framebuffer dimensions to the nearest integer instead of truncating them. (#9538, 9515, #8628)
// 2026-09-03: Added for support for multiple Vulkan contexts with custom loaders. (#6616)
// 2026-04-23: Added support for standard draw callbacks (in platform_io): DrawCallback_ResetRenderState, DrawCallback_SetSamplerLinear, DrawCallback_SetSamplerNearest. (#9378)
// 2026-04-22: *BREAKING CHANGE* redesigned to use separate ImageView + Sampler instead of Combined Image Sampler. This change allows us to facilitate changing samplers, in line with other backends.
