/**
* \file SDL_render.h
*
* \brief Header file for SDL 2D rendering functions.
*
* This API supports the following features:
* * single pixel points
* * single pixel lines
* * filled rectangles
* * texture images
*
* The primitives may be drawn in opaque, blended, or additive modes.
*
* The texture images may be drawn in opaque, blended, or additive modes.
* They can have an additional color tint or alpha modulation applied to
* them, and may also be stretched with linear interpolation.
*
* This API is designed to accelerate simple 2D operations. You may
* want more functionality such as polygons and particle effects and
* in that case you should use SDL's OpenGL/Direct3D support or one
* of the many good 3D engines.
*
* These functions must be called from the main thread.

This would also benefit from some SIMD, since it's just a bunch of multiply-adds fba6e1e3d Removed ResamplerFilterDifference It takes 1 extra multiply to calculate the correct interpolation, but I think the improvement in cache locality (and binary size) outweighs that. 9f7a22fa4 Removed 64-bit handling from AudioConvertByteswap 1f5327a9f Removed future_buffer, left_padding, and right_padding from SDL_AudioStream 71ad52d6d Lowered SDL_GetAudioStreamData to 32 KB No particular reason for this number, but 1 MB was a bit silly 69aec8c91 Fixed the report format for the Razer Wolverine V2 Pro

unnecessary work 88123a510 The history buffer should always have the maximum possible padding frames 96e47f165 Clamp results of GetResampler(AvailableOutput|NeededInput)Frames d2b9c8b80 Fixed maths in testaudiostreamdynamicresample (and just show the actual scale) 14e38b17d Removed assertions from inner ResampleAudio loop 9d413dfdc The history buffer doesn't need to be so large 2788e848f Allow resampling less than 1 frame of input 383084e0a Pre-calculate resampling rate, and use it instead of .freq in most places 40a6a445c Update resample_offset inside ResampleAudio 47fea7f06 Used fixed-point arithmetic in ResampleAudio 7bb4e806e Clear resample_offset in SDL_ClearAudioStream, not SetAudioStreamFormat Not entirely sure if ClearAudioStream is the right place, but SetAudioStreamFormat was the wrong place b9541b9ea Improved ResampleAudio * filterindex2 was off-by-one * Generate ResamplerFilter using doubles * Transpose ResamplerFilter to improve access patterns cdaa19869 Track offset within the current sample when resampling d60ebb06d mouse: Ensure that the dummy default cursor is removed from the cursor list e58c2731f mouse: Free the default cursor when destroyed 789ce17e1 audio: Don't resample in chunks for now. cbab33482 audio: Don't call SDL_AudioStream callbacks for empty data sets. 3e1ae0c86 Clearified the libusb whitelist default logic f4520821e Removed some unnecessary integer casts 0989b7e86 Avoid using designated initializers c6c1e673c Optimized SDL_Convert_*_to_*_Scalar f97b920b3 Optimized SDL_Convert_*_to_*_SSE2 Some of the SDL_Convert_F32_to_*_SSE2 do not explicitly clamp the input, but instead rely on saturating casts. Inputs very far outside the valid [-1.0, 1.0] range may produce an incorrect result, but I believe that is an acceptable trade-off. 300d1ec3e Added audio_convertAccuracy test 32cecc2ea Fixed assertion in audio_convertAudio 33f11e21e Removed assertions in AudioConvert(To|From)Float c2f388fd8 cmake: add SDL_HIDAPI_LIBUSB_SHARED option + test on ci 371cc2d17 wayland: Remove unnecessary flag and state settings fe85e6e75 cocoa: Send a maximized event instead of restored if a deminiaturized window is zoomed ddddcb78c cocoa: Use the close method to hide a miniaturized window be8c42cfd Clarify that a window being 'hidden' means that it is unmapped/ordered out a44338cbc Fix typo in SDL_audiocvt.c f464eb2c5 SDL_hidapi.c: change 'use_libusb_whitelist_default' into a macro. 6607a3cfa Disable cache in python http server 181d5d285 hidapi: Enable libusb support by default. f0f15e365 hidapi: Use a whitelist for libusb when other backends are available c3f7a7dc4 Convert audio using SDL_AUDIO_F32SYS format instead of SDL_AUDIO_F32 796713b9d xxd.py: always write \n line endings 723bcd0a8 SDL_TriggerBreakppoint for riscv arch (both 32/64) version. git-subtree-dir: external/sdl/SDL git-subtree-split: 399bc709b7485bab57880f8261f826f29dc0d7b2
