- Added new input icons for themes, per issue #277.
- Revised MAME and FBA icons for 2013+ by changing screen size and button layouts for consistency with other icons in the set.
- Changed on and off indicators to an oval plus and minus for language and readability purposes, per #273.
Added input and menu icons to align with the reference monochrome theme and address Issue #262 for the Automatic and Systematic themes. Refined some existing menu icons for consistency in design. Optimized PNGs with ImageOptim.
Added the new menu icons for Automatic and Systematic per retroarch-assets #220 and RetroArch #7048.
Added icons for the Thomson T08 and T08D to Automatic and Systematic to fulfill request #218.
Added the Systematic SVG files to the /src/xmb/ directory. Changed the font to Titilium Web Regular. Refreshed the files in the /xmb/systematic directory. Added about 50 new icons to the set.
Based on feedback on the Libretro forum and Issue #180 I added XEGS and
MAME icons. The setting icon has also been changed from a set of gears
to a pair of I/O toggle switches to better reflect the settings that
can be changed in the menus.
