Sam Lantinga adc6875870 Added SDL_copyp to avoid size mismatch when copying values (thanks @1bsyl!) 
Closes https://github.com/libsdl-org/SDL/pull/5811
 2022-06-17 10:22:28 -07:00
Sam Lantinga 1eb247fa2e Fixed building D3D12 renderer with latest mingw-64 2022-06-16 15:44:18 -07:00

Eric Wasylishen e09551bc80 Fix WinRT build 2022-06-11 14:19:01 -07:00
Eric Wasylishen ab81a559f4 Windows DPI scaling/highdpi support 
Adds hint "SDL_WINDOWS_DPI_SCALING" which can be set to "1" to
change the SDL coordinate system units to be DPI-scaled points, rather
than pixels everywhere.

This means windows will be appropriately sized, even when created on
high-DPI displays with scaling.

e.g. requesting a 640x480 window from SDL, on a display with 125%
scaling in Windows display settings, will create a window with an
800x600 client area (in pixels).

Setting this to "1" implicitly requests process DPI awareness
(setting SDL_WINDOWS_DPI_AWARENESS is unnecessary),
and forces SDL_WINDOW_ALLOW_HIGHDPI on all windows.

Ryan C. Gordon 60ddb74cfe video: rework how we prepare a texture framebuffer. 
Now we see if we can create an SDL_Renderer, and if that renderer reports
itself as "accelerated," and added some initial heuristics to the OpenGL
renderer to make better decisions about what qualifies as "accelerated."

This adds some FIXMEs that might be merely hypothetical, and removes the
old OpenGL checks from the video subsystem that probably weren't meaningful
in modern times. This will definitely need to improve the existing list
in the GL renderer, to catch things like llvmpipe, etc.

Reference issue #4624.

SW Renderer: fix invalid read if VSYNC hint is initially set with an empty value (eg "") 
because:
- GeHint return a value pointer.
- SetHint free internally the pointer
- The -now invalid- pointer is re-read

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.
