8340b0f0	2018-10-23T01:34:03	render: Add floating point versions of various draw APIs.
cc56de44	2018-09-23T23:20:40	render: A bunch of high-level improvements. - high-level filters out duplicate render commands from the queue so backends don't have to. - Setting draw color is now a render command, so backends can put color information into the vertex buffer to upload with everything else instead of setting it with slower dynamic data later. - backends can request that they always batch, even for legacy programs, since the lowlevel API can deal with it (Metal, and eventually Vulkan and such...) - high-level makes sure the queue has at least one setdrawcolor and setviewport command before any draw calls, so the backends don't ever have to manage cases where this hasn't been explicitly set yet. - backends allocating vertex buffer space can specify alignment, and the high-level will keep track of gaps in the buffer between the last used positions and the aligned data that can be used for later allocations (Metal and such need to specify some constant data on 256 byte boundaries, but we don't want to waste all that space we had to skip to meet alignment requirements).
5fb67f9f	2018-09-20T15:46:02	render: Move to a batching system for rendering (work in progress).

eb14b635	2018-05-07T19:52:25	Fixed bug 4134 - Render targets lose scale quality after minimizing a fullscreen window Olli-Samuli Lehmus If one creates a window with the SDL_WINDOW_FULLSCREEN_DESKTOP flag, and creates a render target with SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "linear"), and afterwards sets SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "nearest"), after minimizing the window, the scale quality hint is lost on the render target. Textures however do keep their interpolation modes.

9dbe5a96	2017-08-02T13:38:46	Fixed bug 3311 - Broken touch positions with SDL_RenderSetLogicalSize & HIGHDPI on iOS Eric wing Hi, I think I found a bug when using SDL_WINDOW_ALLOW_HIGHDPI with SDL_RenderSetLogicalSize on iOS. I use SDL_RenderSetLogicalSize for all my stuff. I just tried turning on SDL_WINDOW_ALLOW_HIGHDPI on iOS and suddenly all my touch/mouse positions are really broken/far-off-the-mark. I actually don't have a real retina device (still) so I'm seeing this using the iOS simulator with a 6plus template. Attached is a simple test program that can reproduce the problem. It uses RenderSetLogicalSize and draws some moving happy faces (to show the boundaries/space of the LogicalSize and that it is working correctly for that part). When you click/touch, it will draw one more happy face where your button point is. If you comment out SDL_WINDOW_ALLOW_HIGHDPI, everything works as expected. But if you compile with it in, the mouse coordinates seem really far off the mark. (Face appears far up and to the left.) Alex Szpakowski on the mailing list suggests the problem is "I believe this is a bug in SDL_Render?s platform-agnostic mouse coordinate scaling code. It assumes the units of the mouse coordinates are always in pixels, which isn?t the case where high-DPI is involved (regardless of whether iOS is used) ? they?re actually in ?DPI independent? coordinates (which matches the window size, but not the renderer output size)." Additionally, if this is correct, the Mac under Retina is also probably affected too and "as well as any other platform SDL adds high-dpi support for in the future".

2a2c8d42	2016-04-21T03:16:44	Initial shot at a renderer target for Apple's Metal API. This isn't complete, but is enough to run testsprite2. It's currently Mac-only; with a little work to figure out how to properly glue in a Metal layer to a UIView, this will likely work on iOS, too. This is only wired up to the configure script right now, and disabled by default. CMake and Xcode still need their bits filled in as appropriate.

0e45984f	2015-06-21T17:33:46	Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

b88ca1b4	2015-02-10T16:28:56	the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here. Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture. More info on the confusion https://bugs.freedesktop.org/show_bug.cgi?id=16802

defd90b6	2014-04-19T13:15:41	Render: Allow empty cliprect. This fixes an issue where an empty cliprect is treated the same as a NULL cliprect, causing the render backends to disable clipping. Also adds a new API, SDL_RenderIsClipEnabled(render) that allows you to differentiate between: - SDL_RenderSetClipRect(render, NULL) - SDL_Rect r = {0,0,0,0}; SDL_RenderSetClipRect(render, &r); Fixes https://bugzilla.libsdl.org/show_bug.cgi?id=2504

dad42067	2013-08-12T11:13:50	Fixes #2022, do not resume on Android when surfaceChanged If the app is in landscape mode and the user presses the power button, a pause is followed immediately by a surfaceChanged event because the lock screen is shown in portrait mode. This triggers a "false" resume. So, we just pause and resume following the onWindowFocusChanged events. Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before blocking the event pump.
