Eric Wasylishen b786c100 2021-11-26T19:45:16 SDL_render_gl.c: GL_RunCommandQueue: always set viewport_dirty on macOS Without this, moving the window changes the viewport and causes contents to render stretched. Fixes #1504
Ryan C. Gordon 86c0cf2b 2021-11-26T14:31:20 software: Draw a single pixel for a line with the same start/end point. Otherwise it would drop it, which seems like a bug to me, as it normally fills the endpoint on lines. Reference #2006.

Sylvain 49369142 2021-11-21T17:40:48 Fixed bug #4625: with integer scale, viewport (as reported by SDL_RenderGetViewport) becomes -2147483648x-2147483648 0 isn't valid scale. Min integer scale is 1.0f
Sam Lantinga 9ec2b351 2021-11-15T13:45:53 Fixed the GLES2 shader count to be in sync with the enum

Sylvain 92f2fdfc 2021-11-15T09:36:18 GLES2: batch non joined lines (see #4964)
Sylvain 17f156fa 2021-11-15T09:08:09 Fixed bug #4964 - opengles2 & batching = conjoined lines put back the initial switch case because groups of joined lines cannot be batched.

Sylvain a50ca98e 2021-11-13T14:48:36 Fixed bug #4625 - SDL_RenderSetLogicalSize issues viewport becomes -2147483648x-2147483648 when logical_w/h is greater than window size. division should be done with floats
Misa 3bf7994f 2021-09-27T14:38:12 Add and use `SDL_FALLTHROUGH` for fallthroughs Case fallthrough warnings can be suppressed using the __fallthrough__ compiler attribute. Unfortunately, not all compilers have this attribute, or even have __has_attribute to check if they have the __fallthrough__ attribute. [[fallthrough]] is also available in C++17 and the next C2x, but not everyone uses C++17 or C2x. So define the SDL_FALLTHROUGH macro to deal with those problems - if we are using C++17 or C2x, it expands to [[fallthrough]]; else if the compiler has __has_attribute and has the __fallthrough__ attribute, then it expands to __attribute__((__fallthrough__)); else it expands to an empty statement, with a /* fallthrough */ comment (it's a do {} while (0) statement, because users of this macro need to use a semicolon, because [[fallthrough]] and __attribute__((__fallthrough__)) require a semicolon). Clang before Clang 10 and GCC before GCC 7 have problems with using __attribute__ as a sole statement and warn about a "declaration not declaring anything", so fall back to using the /* fallthrough */ comment if we are using those older compiler versions. Applications using SDL are also free to use this macro (because it is defined in begin_code.h). All existing /* fallthrough */ comments have been replaced with this macro. Some of them were unnecessary because they were the last case in a switch; using SDL_FALLTHROUGH in those cases would result in a compile error on compilers that support __fallthrough__, for having a __attribute__((__fallthrough__)) statement that didn't immediately precede a case label.
Sam Lantinga abc12a83 2021-11-11T15:58:44 Revert "Add and use `SDL_FALLTHROUGH` for fallthroughs" This reverts commit 66a08aa3914a98667f212e79b4f0b9453203d656. This causes problems with older compilers: https://github.com/libsdl-org/SDL/pull/4791#issuecomment-966630997

Sam Lantinga 6c4b4ee7 2021-11-10T09:41:43 Don't assert on API parameters This causes lots of spam in test automation and it's not clear it's useful to developers. If we need this level of validation, we should add a log category for it.
Sam Lantinga 3a31a450 2021-11-10T05:24:31 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. Fixes https://github.com/libsdl-org/SDL/issues/4933

Sylvain b7933945 2021-10-25T13:46:40 SDL_Renderer: make clear that we use render geometry for fillrect/copy/copyex when there is no specific back-end implementation (currently software, PSP, directfb)

Sylvain 502e9c3b 2021-10-24T17:16:49 SDL_Renderer simplifications: - Factorize PrepQueueCmdDraw{,DrawTexture,Solid) into one single function - Change SDL_Texture/Renderer r,g,b,a Uint8 into an SDL_Color, so that it can be passed directly to RenderGeometry - Don't automatically queue a SET_DRAW_COLOR cmd for RenderGeometry (and update GLES2 renderer)

Sylvain 99a34643 2021-09-24T09:42:04 OpenGLES2: LINES and POINTS successive commands are combined into a single draw call (using the same case for DRAW_GEOMETRY)
Sylvain f0cdc1d0 2021-09-24T09:38:25 OpenGLES2: remove FillRects, since it's can be done with RenderGeometry
Sylvain 37c39d5c 2021-09-23T22:45:45 Use geometry to implement FillRects

Sylvain 77acd44f 2021-10-01T22:30:51 DirectFB: fixed creation of palette textures
Ryan C. Gordon 114d1d46 2021-09-27T23:18:25 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.
Northfear 14f22519 2021-09-26T18:11:22 Use SDL_calloc for allocation of gxm_texture

Northfear 7080bc2a 2021-09-20T23:02:01 Fallback to SCE_KERNEL_MEMBLOCK_TYPE_USER_RW_UNCACHE if CDRAM texture allocation fails
Ryan C. Gordon ca9a3217 2021-09-19T15:47:24 render: GL/GLES now draw lines almost perfectly matching software renderer. One place known to differ in a significant way is a single line segment that starts and ends on the same point; the GL renderers will light up a single pixel here, whereas the software renderer will not. My current belief is this is a bug in the software renderer, based on the wording of the docs: "SDL_RenderDrawLine() draws the line to include both end points." You can see an example program that triggers that difference in Bug #2006. As it stands, the GL renderers might _also_ render diagonal lines differently, as the the Bresenham step might vary between implementations (one does three pixels and then two, the other does two and then three, etc). But this patch causes those lines to start and end on the correct pixel, and that's the best we can do, and all anyone really needs here. Not closing any bugs with this patch (yet!), but here are several that it appears to fix. If no other corner cases pop up, we'll call this done. Reference Bug #2006. Reference Bug #1626. Reference Bug #4001. ...and probably others...
Ryan C. Gordon 857cc7c0 2021-09-19T00:05:21 render: constified some local variables in SDL_AllocateRenderVertices.
Ryan C. Gordon 5faea84c 2021-09-18T11:54:25 render: Mark viewport/cliprect dirty when window is resized. Fixes #4751.
Ivan Epifanov 79ec8986 2021-09-16T12:47:45 Vita: refactor gxm texture render and add SDL_RenderGeometry support
Misa 4a994733 2021-09-14T15:51:17 `SDL_RenderSetVSync()`: Restrict `vsync` to 0 or 1 In the future, we might want to support special swap intervals. To prevent applications from expecting nonzero values of vsync to be the same as "on", fail with SDL_Unsupported() if the value passed is neither 0 nor 1.
Misa 4549769d 2021-03-07T15:20:45 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.
Ivan Epifanov 10d3df44 2021-09-09T12:46:28 Vita: fix copyright dates
Ryan C. Gordon d49d955d 2021-09-08T11:44:17 render: SDL_RenderGeometry should still render when hidden, in most cases. (otherwise render targets may fail, etc...the check is a legacy helper for iOS apps that crash if you try to use OpenGL while in the background.)

Sylvain e426bb80 2021-08-20T07:50:30 Fixed bug #4671 - D3D_QueueGeometry: use "count / 3" (Thanks alittlesail!)
Sylvain ae5336a3 2021-08-19T14:03:10 Fixed bug #4669: D3D_QueueGeometry: -0.5f offset position of vertexs This similar to D3D_QueueCopy positions
