End the scene before resetting the D3D device, since we'll start with BeginScene after that.
If we don't do this, we'll end up with unbalanced Begin/End scene pairs which causes D3DERR_INVALIDCALL in the present.

direct3d: Remove unnecessary render target support check.
Direct3D 9 dictates that caps.NumSimultaneousRTs must always be at least 1,
which is to say that Direct3D 9 level hardware must always support render
targets.
(caps.NumSimultaneousRTs is meant to show if you can draw to multiple render
targets in a single draw call.)
We had already hardcoded SDL_RENDERER_TARGETTEXTURE as available earlier in
the function anyhow.
Fixes #4781.

Add `SDL_RenderSetVSync()`
Currently, if an application wants to toggle VSync, they'd have to tear
down the renderer and recreate it. This patch fixes that by letting
applications call SDL_RenderSetVSync().
This is the same as the patch in #3673, except it applies to all
renderers (including PSP, even thought it seems that the VSync flag is
disabled for that renderer). Furthermore, the renderer flags also change
as well, which #3673 didn't do. It is also an API instead of using hint
callbacks (which could be potentially dangerous).
Closes #3673.

direct3d: Commit viewport state before clearing, attempt 2.
This reintroduces the fix from 0e16ee8330606603, but just marks
the viewport state as dirty after a clear that needs to expand the
viewport to fill the render target, as we'll need to also reset
the orthographic projection state elsewhere, and that won't
happen if we clear the dirty flag here.

Fixed bug 4991 - Pixel shader problem when recreating a texture for direct3d renderer
cmediaplayer
Hi, i already mentioned in the SDL discourse a bug that recreating of a texture occours pixel shader problem on direct3d renderer. There is no problem for direct3d11. You can see the issue by using my app named C Media Player which is available for Windows for free using my web site www.cmediaplayer.com. Just follow the steps:
*Open a media file
*When playing the file change the scale quality under the video menu.
*You will see the problem.

Fixed bug 4914 - Expose SDL_ScaleMode and add SDL_SetTextureScaleMode/SDL_GetTextureScaleMode
Konrad
This was something rather trivial to add, but asked at least several times before (I did google about it as well).
It should be possible to dynamically change scaling mode of the texture. It is actually trivial task, but until now it was only possible with a hint before creating a texture.
I needed it for my game as well, so I took the liberty of writing it myself.
This patch adds following functions:
SDL_SetTextureScaleMode(SDL_Texture * texture, SDL_ScaleMode scaleMode);
SDL_GetTextureScaleMode(SDL_Texture * texture, SDL_ScaleMode *scaleMode);
That way you can change texture scaling on the fly.

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.

Fixed bug 1878 - Scaled texture draws with filtering produce wrapping artifacts.
Yuri K. Schlesner
When using texture filtering, there are filtering artifacts visible on the edges of scaled textures, where the texture filtering pulls in texels from the other side of the texture. Using clamping texture modes wouldn't completely fix this since source rectangles don't need to cover the whole texture. (See screenshot attached in next post.)
The opengl driver uses clamping on textures and so avoid this at least in the cases where the source rect is the whole texture. The direct3d driver does not and so has problems in every case. I'm not sure if it can actually completely be fixed, but at least enabling clamping for direct3d would be one step in the right direction.

Updated SDL's YUV support, many thanks to Adrien Descamps
New functions get and set the YUV colorspace conversion mode:

SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.

Fixed bug 3345 - SDL_RenderClear inconsistency with ClipRect
Simon Hug
The description of the SDL_RenderClear function in the SDL_render.h header says the following:
"This function clears the entire rendering target, ignoring the viewport."
The word "entire" implies that the clipping rectangle set with SDL_RenderSetClipRect also gets ignored. This is left somewhat ambiguous if only the viewport is mentioned. Minor thing, but let's see what the implementations actually do.
The software renderer ignores the clipping rectangle when clearing. It even has a comment on this: /* By definition the clear ignores the clip rect */
Most other render drivers (opengl, opengles, opengles2, direct3d, and psp [I assume. Can't test it.]) use the scissor test for the ClipRect and don't disable it when clearing. Clearing will only happen within the clipping rectangle for these drivers.
An exception is direct3d11 which uses a clear function that ignores the scissor test.

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().

Fixed bug 2625 - Direct3D9 with SDL_TEXTUREACCESS_TARGET textures causes an application crash
Roberto
I have debugged the code checking the function calls when Direct3D is the renderer, remember that with software and OpenGL renderers, this issue is not happening.
- Create the texture:
SDL_Texture *pTex = SDL_CreateTexture(pRenderer, iFormat, SDL_TEXTUREACCESS_TARGET, pSurf->w, pSurf->h);
- Update the texture:
SDL_UpdateTexture(pTex, NULL, pSurf->pixels, pSurf->pitch);
SDL_render.c, SDL_UpdateTexture(): return renderer->UpdateTexture(renderer, texture, rect, pixels, pitch);
SDL_render_d3d.c, D3D_UpdateTexture(): if (D3D_UpdateTextureRep(data->device, &texturedata->texture, texture->format, rect->x, rect->y, rect->w, rect->h, pixels, pitch) < 0) {
SDL_render_d3d.c, D3D_UpdateTextureRep(): if (D3D_CreateStagingTexture(device, texture) < 0) {
SDL_render_d3d.c, D3D_CreateStagingTexture(): result = IDirect3DDevice9_CreateTexture(..., D3DPOOL_SYSTEMMEM, ...) --> FAIL! with INVALIDCALL code
After checking a bit the Microsoft documentation, I found this:
D3DUSAGE_RENDERTARGET can only be used with D3DPOOL_DEFAULT. (https://msdn.microsoft.com/en-us/library/windows/desktop/bb172625%28v=vs.85%29.aspx)
The call that fails, is using D3DUSAGE_RENDERTARGET with D3DPOOL_SYSTEMMEM which is unsupported, hence the INVALIDCALL return code.

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.

Fixed bug 2685 - SDL_RenderReadPixels() doesn't work with offscreen targets
Andreas Falkenhahn
SDL_RenderReadPixels() doesn't seem to work when trying to read pixels from a texture that has been created using SDL_TEXTUREACCESS_TARGET and has been selected as the render target using SDL_SetRenderTarget().
I am attaching a small program that demonstrates the issue. I get the following result here:
READ PIXEL RETURN: 0 --- COLOR CHECK: ff000000
But it should be:
READ PIXEL RETURN: 0 --- COLOR CHECK: ffff0000

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);

Fixed bug 2385 - error: unknown type name 'IDirect3DDevice9'
Sandu Liviu Catalin
I'm unable to compile the latest SDL (directly from the repository) even though I disabled every DirectX option since I don't need DirectX.
I allways het these errors:
D:\DevLibs\SDL\src\render\direct3d\SDL_render_d3d.c:1897:1: error: unknown type name 'IDirect3DDevice9'
D:\DevLibs\SDL\src\render\direct3d\SDL_render_d3d.c:1898:25: error: unknown type name 'SDL_Renderer'

Diagonal flipping with RenderCopyEx
Ivan Rubinson
As it turns out, it was impossible to render a texture flipped diagonally (both vertically and horizontally) with one RenderCopyEx call.
With help from #SDL @ freenode, we came up with a fix.

Fixed bug 2162 - SDL_RenderClear not clearing entire render target
Kevin Wells
Overview:
SDL_RenderClear is only clearing part of a texture when it is the render target and a different size than the screen.
Steps to Reproduce:
1) This only occurs with the render driver set to direct3d, so: SDL_SetHint(SDL_HINT_RENDER_DRIVER,"direct3d")
Also, my window was 1280x720.
2) Create a texture for a render target with a resolution of 1024x1024:
texture=SDL_CreateTexture(main_window.renderer,SDL_PIXELFORMAT_RGBA8888,SDL_TEXTUREACCESS_TARGET,1024,1024);
SDL_SetTextureBlendMode(texture,SDL_BLENDMODE_BLEND);
3) Target the texture for rendering: SDL_SetRenderTarget(main_window.renderer,texture);
4) Set the draw color to whatever you want (problem occurs with both 0,0,0,0 and 0,0,0,255 among others) and then clear the render target:
SDL_SetRenderDrawColor(main_window.renderer,0,0,0,0);
SDL_RenderClear(main_window.renderer);
Actual Results:
Only about the top 3/4s of the texture gets cleared on calling SDL_RenderClear. The bottom 1/4 or so does not clear.
Expected Results:
Entire render target should be cleared.

Call AddRef() on the device so it doesn't accidentally get released from underneath the caller.
