renderer: Always use the output size when updating the main view

The main view always reflects the size of the output, so don't use the dimensions of the currently bound render target texture when updating it, or it will reflect an incorrect size when the render target texture is unbound.

(cherry picked from commit 8aa5b97bb5)

+# Introduction to SDL with MinGW
+
+Without getting deep into the history, MinGW is a long running project that aims to bring gcc to Windows. That said, there's many distributions, versions, and forks floating around. We recommend installing [MSYS2](https://www.msys2.org/), as it's the easiest way to get a modern toolchain with a package manager to help with dependency management. This would allow you to follow the MSYS2 section below. 
+
+Otherwise you'll want to follow the "Other Distributions" section below.
+
+We'll start by creating a simple project to build and run [hello.c](hello.c).
+
+# MSYS2
+
+Open the `MSYS2 UCRT64` prompt and then ensure you've installed the following packages. This will get you working toolchain, CMake, Ninja, and of course SDL3.
+
+```sh
+pacman -S mingw-w64-ucrt-x86_64-gcc mingw-w64-ucrt-x86_64-ninja mingw-w64-ucrt-x86_64-cmake mingw-w64-ucrt-x86_64-sdl3
+```
+
+## Create the file CMakeLists.txt
+```cmake
+cmake_minimum_required(VERSION 3.26)
+project(hello C CXX)
+
+find_package(SDL3 REQUIRED)
+
+add_executable(hello)

+
+## Run:
+
+The executable is in the `build` directory:
+```sh
+cd build
+./hello
+```
+
+# Other Distributions
+
+Things can get quite complicated with other distributions of MinGW. If you can't follow [the cmake intro](INTRO-cmake.md), perhaps due to issues getting cmake to understand your toolchain, this section should work.

+## Acquire SDL
+
+Download the `SDL3-devel-<version>-mingw.zip` asset from [the latest release.](https://github.com/libsdl-org/SDL/releases/latest) Then extract it inside your project folder such that the output of `ls SDL3-<version>` looks like `INSTALL.md  LICENSE.txt  Makefile  README.md  cmake  i686-w64-mingw32  x86_64-w64-mingw32`.
+
+## Know your Target Architecture
+
+It is not uncommon for folks to not realize their distribution is targeting 32bit Windows despite things like the name of the toolchain, or the fact that they're running on a 64bit system. We'll ensure we know up front what we need:
+
+Create a file named `arch.c` with the following contents:
+```c
+#include <stddef.h>
+#include <stdio.h>
+int main() {
+    #if defined(__x86_64__) || defined(_M_X64) || defined(i386) || defined(__i386__) || defined(__i386) || defined(_M_IX86)
+        size_t ptr_size = sizeof(int*);
+        if (4 == ptr_size) puts("i686-w64-mingw32");
+        else if (8 == ptr_size) puts("x86_64-w64-mingw32");
+        else puts("Unknown Architecture");
+    #else
+        puts("Unknown Architecture");
+    #endif
+    return 0;
+}
+```
+
+Then run
+
+```sh
+gcc arch.c
+./a.exe
+```
+
+This should print out which library directory we'll need to use when compiling, keep this value in mind, you'll need to use it when compiling in the next section as `<arch>`. If you get "Unknown Architecture" please [report a bug](https://github.com/libsdl-org/SDL/issues).
+
+
+## Build and Run
+
+Now we should have everything needed to compile and run our program. You'll need to ensure to replace `<version>` with the version of the release of SDL3 you downloaded, as well as use the `<arch>` we learned in the previous section.
+
+```sh
+gcc hello.c -o hello.exe -I SDL3-<version>/<arch>/include -L SDL3-<version>/<arch>/lib -lSDL3 -mwindows 
+cp SDL3-<version>/<arch>/bin/SDL3.dll SDL3.dll

-To reconcile platform differences in their approach to high-density scaling, SDL provides the following interfaces:
-- `SDL_GetWindowSize()`          retrieves the window dimensions in native coordinates.
-- `SDL_GetWindowSizeInPixels()`  retrieves the window dimensions in pixels-addressable.
-- `SDL_GetDisplayContentScale()` retrieves the suggested amplification factor when drawing in native coordinates.
-- `SDL_GetWindowDisplayScale()`  retrieves the suggested amplification factor when drawing in pixels-addressable.
-- `SDL_GetWindowPixelDensity()`  retrieves how many addressable pixels correspond to one unit of native coordinates.
-- `SDL_EVENT_WINDOW_PIXEL_SIZE_CHANGED`    is emitted when the value retrievable from `SDL_GetWindowSizeInPixels()` changes.
-- `SDL_EVENT_WINDOW_DISPLAY_SCALE_CHANGED` is emitted when the value retrievable from `SDL_GetWindowDisplayScale()` changes.

 ## Explanation
 
 Displays now have a content display scale, which is the expected scale for content based on the DPI settings of the display. For example, a 4K display might have a 2.0 (200%) display scale, which means that the user expects UI elements to be twice as big on this display, to aid in readability. You can query the display content scale using `SDL_GetDisplayContentScale()`, and when this changes you get an `SDL_EVENT_WINDOW_DISPLAY_SCALE_CHANGED` event.
@@ -34,3 +8,33 @@ Displays now have a content display scale, which is the expected scale for conte
 The window size is now distinct from the window pixel size, and the ratio between the two is the window pixel density. If the window is created with the `SDL_WINDOW_HIGH_PIXEL_DENSITY` flag, SDL will try to match the native pixel density for the display, otherwise it will try to have the pixel size match the window size. You can query the window pixel density using `SDL_GetWindowPixelDensity()`. You can query the window pixel size using `SDL_GetWindowSizeInPixels()`, and when this changes you get an `SDL_EVENT_WINDOW_PIXEL_SIZE_CHANGED` event. You are guaranteed to get a `SDL_EVENT_WINDOW_PIXEL_SIZE_CHANGED` event when a window is created and resized, and you can use this event to create and resize your graphics context for the window.
 
 The window has a display scale, which is the scale from the pixel resolution to the desired content size, e.g. the combination of the pixel density and the content scale. For example, a 3840x2160 window displayed at 200% on Windows, and a 1920x1080 window with the high density flag on a 2x display on macOS will both have a pixel size of 3840x2160 and a display scale of 2.0.  You can query the window display scale using `SDL_GetWindowDisplayScale()`, and when this changes you get an `SDL_EVENT_WINDOW_DISPLAY_SCALE_CHANGED` event.

+
+Observe the difference between the approaches taken by macOS and Windows:
+- The Windows and Android coordinate system always deals in physical device pixels, high DPI support is achieved by providing a content scale that tells the developer to draw objects larger. Ignoring this scale factor results in graphics appearing tiny.
+- The macOS and iOS coordinate system always deals in window coordinates, high DPI support is achieved by providing an optional flag for the developer to request more pixels. Omitting this flag results in graphics having low detail.
+- On Linux, X11 uses a similar approach to Windows and Wayland uses a similar approach to macOS.
+
+## Solution
+
+Proper high DPI support takes into account both the content scale and the pixel density.
+
+First, you'd create your window with the `SDL_WINDOW_HIGH_PIXEL_DENSITY` flag, assuming you want the highest detail possible. Then you'd get the window display scale to see how much your UI elements should be enlarged to be readable.
+
+If you're using the SDL 2D renderer, SDL provides the function `SDL_ConvertEventToRenderCoordinates()` to convert mouse coordinates between window coordinates and rendering coordinates, and the more general functions `SDL_RenderCoordinatesFromWindow()` and `SDL_RenderCoordinatesToWindow()` to do other conversion between them.
+
+If you're not using the 2D renderer, you can implement this yourself using `SDL_GetWindowPixelDensity()` as scale factor to convert from window coordinates to pixels.
+
+Finally you'll want to test on both Windows and macOS if possible to make sure your high DPI support works in all environments.
