Changes 2.0.6:
General:
* Added cross-platform Vulkan graphics support in SDL_vulkan.h
SDL_Vulkan_LoadLibrary()
SDL_Vulkan_GetVkGetInstanceProcAddr()
SDL_Vulkan_GetInstanceExtensions()
SDL_Vulkan_CreateSurface()
SDL_Vulkan_GetDrawableSize()
SDL_Vulkan_UnloadLibrary()
This is all the platform-specific code you need to bring up Vulkan on all SDL platforms. You can look at an example in test/testvulkan.c
* Added SDL_ComposeCustomBlendMode() to create custom blend modes for 2D rendering
* Added SDL_HasNEON() which returns whether the CPU has NEON instruction support
* Added support for many game controllers, including the Nintendo Switch Pro Controller
* Added support for inverted axes and separate axis directions in game controller mappings
* Added functions to return information about a joystick before it's opened:
SDL_JoystickGetDeviceVendor()
SDL_JoystickGetDeviceProduct()
SDL_JoystickGetDeviceProductVersion()
SDL_JoystickGetDeviceType()
SDL_JoystickGetDeviceInstanceID()
* Added functions to return information about an open joystick:
SDL_JoystickGetVendor()
SDL_JoystickGetProduct()
SDL_JoystickGetProductVersion()
SDL_JoystickGetType()
SDL_JoystickGetAxisInitialState()
* Added functions to return information about an open game controller:
SDL_GameControllerGetVendor()
SDL_GameControllerGetProduct()
SDL_GameControllerGetProductVersion()
* Added SDL_GameControllerNumMappings() and SDL_GameControllerMappingForIndex() to be able to enumerate the built-in game controller mappings
* Added SDL_LoadFile() and SDL_LoadFile_RW() to load a file into memory
* Added SDL_DuplicateSurface() to make a copy of a surface
* Added an experimental JACK audio driver
* Implemented non-power-of-two audio resampling, optionally using libsamplerate to perform the resampling
* Added the hint SDL_HINT_AUDIO_RESAMPLING_MODE to control the quality of resampling
* Added the hint SDL_HINT_RENDER_LOGICAL_SIZE_MODE to control the scaling policy for SDL_RenderSetLogicalSize():
"0" or "letterbox" - Uses letterbox/sidebars to fit the entire rendering on screen (the default)
"1" or "overscan" - Will zoom the rendering so it fills the entire screen, allowing edges to be drawn offscreen
* Added the hints SDL_HINT_MOUSE_NORMAL_SPEED_SCALE and SDL_HINT_MOUSE_RELATIVE_SPEED_SCALE to scale the mouse speed when being read from raw mouse input
* Added the hint SDL_HINT_TOUCH_MOUSE_EVENTS to control whether SDL will synthesize mouse events from touch events

Remove delay as there is already an inherent delay in writing audio.

audio_prinfo needs 'struct' on NetBSD.
|
|
Use correct prinfo.
|
|
Inform upper layer of blocksize
