Minecraft and other applications can render with alpha=0 in the backbuffer, which causes the content to appear transparent/gray when blitted to the Metal swapchain (CAMetalLayer). This is because Metal's compositor respects the alpha channel of the swapchain content. Fix this by forcing the alpha channel to 1.0 in both blit shader paths: - vk_meta_blit_resolve.c: For the meta blit path (vk_meta_blit_image2) - u_simple_shaders.c: For the util_blitter path Additionally, force format conversion blits (RGBA->BGRA) to use util_blitter instead of vk_meta_blit, as the meta path has intermittent black flashing issues on Metal that still need investigation. Also removes debug fprintf statements added during debugging.
