video_core: shorten GetGLSLVersionString
video_core: make GLES version and extensions consistent
video_core: move some logic to LoadShader
video_core: deduplicate fragment shader precision specifier
Allows capturing screenshot at the current internal resolution (native for software renderer), but a setting is available to capture it in other resolutions. The screenshot is saved to a single PNG in the current layout.
* renderer_opengl: Namespace OpenGL code
Namespaces all OpenGL code under the OpenGL namespace.
Prevents polluting the global namespace and allows clear distinction
between other renderers' code in the future.
* Also namespace TextureCubeConfig
…class
Makes the global a member of the RendererBase class. We also change this
to be a reference. Passing any form of null pointer to these functions
is incorrect entirely, especially given the code itself assumes that the
pointer would always be in a valid state.
This also makes it easier to follow the lifecycle of instances being
used, as we explicitly interact the renderer with the rasterizer, rather
than it just operating on a global pointer.
* Fixed crash when right eye isn't available
* Enabled swap screens in stereo views. Fixed window alignment in stereo
views to handle all screen aspect ratios.
* Minor code cleanup and clang fomat updates.
* Minor cleanup of swapped and aspect ratio code
Now based on std::chrono, and also works in terms of emulated time
instead of frames, so we can in the future frame-limit even when the
display is disabled, etc.
The frame limiter can also be enabled along with v-sync now, which
should be useful for those with displays running at more than 60 Hz.
On SDL2 this allows it to use SDL_GL_GetProcAddress() instead of the
default function loader, and fixes a crash when using apitrace with an
EGL context.
On Qt we will need to migrate from QGLWidget to QOpenGLWidget and
QOpenGLContext before we can use gladLoadGLLoader() instead of
gladLoadGL(), since the former doesn’t expose a function loader.
The nVidia driver is *extremely* spammy on this category, sending a
message on every buffer or texture upload, slowing down the emulator and
making the log useless.
This removes explicit checks sprinkled all over the codebase to instead
just have the SW rasterizer expose an implementation with no-ops for
most operations.
The main advantage of switching to glad from glLoadGen is that, apart
from being actively maintained, it supports a customizable entrypoint
loader function, which makes it possible to also support OpenGL ES.
This is exposed in the GUI as a new "CiTrace Recording" widget.
Playback is implemented by a standalone 3DS homebrew application (which only runs reliably within Citra currently; on an actual 3DS it will often crash still).
