RetroArch/gfx/gfx_display.c
Jason Breitweiser 11d9a841f3
This change allows playlist icons to be replaced with Logos. (#16758) 
* This change allows playlist icons to be replaced with Logos. the art is loaded to the Thumbnail Named_Logos folder. It is treated the same as other thumbnails for naming and for automatic download. There is a settings menu option to turn it on and off. It is off by default. This only applies to the xmb menu driver.

* Removed commented out code against the style guide.

* Code cleanup for C89 compatibitity

* Cleaned up errors from Automated CI.

* Cleaned up comments.

* Update gfx_display.c

change strcpy to strlcpy

* Update gfx_thumbnail_path.c

fix code formatting

* Update xmb.c

code formatting changes

* > This blurring is a problem because (by design) the corners
* of the sliced texture are drawn at native resolution,
* whereas the middle segments are stretched to fit the
* requested dimensions. Consequently, the corners are sharp
* while the middle segments are blurred.
* > When *upscaling* the middle segments (i.e. display size
* greater than texture size), the visible effects of this
* are mostly imperceptible.
* > When *downscaling* them, however, the interpolation effects
* completely dominate the output image - creating an ugly
* transition between the corners and middle parts.
* > Since this is a property of hardware rendering, it is not
* practical to fix this 'properly'...
