Sam Lantinga d744aafb05 Added support for simulated vsync in the renderer 
This kicks in if the platform doesn't support vsync directly, or if the present fails for some reason (e.g. minimized on some platforms)

Ethan Lee a28f426acb render: Only update size/scale/viewport when moving to a new display, rather than all window movement. 
We really only care about DPI changes here, so this both reduces work and also avoids weird cases where viewport state can be corrupted by trivial window events. This doesn't _completely_ get rid of the issue but this is somewhat intentional, since apps will definitely want to do a full reset when changing displays anyhow (otherwise DPI/adapter changes will screw things up, and that's out of our control as long as both window size and drawable size are exposed at the same time.

Note that OpenGL still captures window events because of weird platform-specific issues like macOS and viewport stretching!

Fixes #5949

testwm2: Fix video modes menu hit detection when highdpi or logical size used (#4936) 
* SDLTest_CommonDrawWindowInfo: log SDL_RenderGetScale, SDL_RenderGetLogicalSize

* testwm2: fix video modes menu hit detection in High DPI cases

- also when logical size is specified, e.g.
  `--logical 640x480 --resizable --allow-highdpi`

* add function to determine logical coordinates of renderer point when given window point

* change since to the targeted milestone

* fix typo

* rename for consistency

* Change logical coordinate type to float, since we can render with floating point precision.

* add function to convert logical to window coordinates

* testwm2: use new SDL_RenderWindowToLogical

* SDL_render.c: alternate SDL_RenderWindowToLogical/SDL_RenderLogicalToWindow

Misa 4a9947336c 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.
 2021-09-14 16:18:02 -07:00
Misa 4549769d7d 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.

David Gow 4077f7a2d9 Update the Renderer dpi_scale on SIZE_CHANGED event (fix #4580) 
The Renderer logical scaling code scales mouse coordinates, and needs to
take the window DPI into account on HIGHDPI windows. However, the
variable which tracks this, renderer->dpi_scale, is set once when the
renderer is created, and then not updated. In the event that the window
is moved to another screen, or the screen DPI otherwise changes, this
will be outdates, and potentially the coordinates will be all wrong.

So let's update the dpi_scale on the SIZE_CHANGED event: it's at least a
possibility that this will be issued on some OSes when DPI changes, and
it's otherwise already handled by SDL_Renderer's event filter.
