feat: map kRoleAlwaysOnTop z-order level to always-on-top surface role OS-20685 - #149
Merged
Conversation
…e OS-20685 Add the always-on-top role (value 5) to the bs_z_order_v2 role enum so the generated protocol headers expose BS_Z_ORDER_V2_ROLE_ALWAYS_ON_TOP for the Ozone client. This layer is used for supervisor on-screen displays such as TV controls for brightness, colour and volume. Emit bs_z_order_v2_set_role with BS_Z_ORDER_V2_ROLE_ALWAYS_ON_TOP from XdgToplevel::SetZOrder so an Ozone window can be assigned the always-on-top role.
