Isso \u00e9 importante para sistemas onde um aplicativo renderiza quadros em uma GPU, enquanto o compositor ou a sa\u00edda de exibi\u00e7\u00e3o operam atrav\u00e9s de outra GPU. Anteriormente, o cliente n\u00e3o tinha uma maneira normal de saber antecipadamente se o compositor aceitaria com sucesso um buffer DMA-BUF criado em um dispositivo que n\u00e3o \u00e9 o \"principal\".<\/p>\n<\/li>\n<li>\n<p><strong>Suporte adicionado para Windows BT.2100 image description request no color-management-v1.<\/strong><br \/>\nEssa mudan\u00e7a refere-se \u00e0 infraestrutura de gerenciamento de cores e HDR. Ela permite que compositores do Wayland implementem o tratamento especial de conte\u00fado HDR que utiliza a descri\u00e7\u00e3o de imagem BT.2100 compat\u00edvel com o Windows. O significado pr\u00e1tico \u00e9 mais um passo em dire\u00e7\u00e3o \u00e0 transmiss\u00e3o mais previs\u00edvel de metadados HDR e caracter\u00edsticas de cores entre aplicativos e o compositor.<\/p>\n<\/li>\n<li>\n<p><strong>Adicionado protocolo experimental xx-fractional-scale-v2.<\/strong><br \/>\nO novo protocolo de escalonamento fracion\u00e1rio deve corrigir algumas limita\u00e7\u00f5es da primeira vers\u00e3o. Ele permite que clientes e compositores utilizem um espa\u00e7o de coordenadas separado para troca de coordenadas de superf\u00edcies, tornando a intera\u00e7\u00e3o em escalas como 125%, 150% ou 175% mais precisa. Por enquanto, este \u00e9 um protocolo experimental, ou seja, sua API ainda n\u00e3o deve ser considerada totalmente estabilizada.<\/p>\n<\/li>\n<li>\n<p><strong>O desenvolvimento de modelos de protocolos staged\/experimentais continuou.<\/strong><br \/>\nOs Protocolos Wayland dividem as extens\u00f5es em est\u00e1gios: os protocolos experimentais podem mudar de forma incompat\u00edvel, os protocolos em est\u00e1gio s\u00e3o destinados a testes mais amplos, enquanto os protocolos est\u00e1veis s\u00e3o considerados suficientemente testados para uso a longo prazo. Portanto, a apari\u00e7\u00e3o do xx-fractional-scale-v2 na \u00e1rea experimental n\u00e3o significa suporte imediato e massivo em todos os ambientes, mas sim o in\u00edcio de testes padronizados da nova esquem\u00e1tica de escalonamento.<\/p>\n<\/li>\n<\/ul>\n<p>No geral <strong>Protocolos Wayland 1.49<\/strong> \u2014 lan\u00e7amento de infraestrutura para desenvolvedores de compositores, kits de ferramentas e a pilha gr\u00e1fica de drivers.
