Subject: Update raylib files and Makefile for Pi 4 testing
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=47ad4679e4625ff34239ee796b78b89b8455bb71;p=pistorm

Update raylib files and Makefile for Pi 4 testing

The headless graphics driver for the Raspberry Pi 4 is screwed up and only does software rendering, so any kind of performant RTG on Pi 4 will require some flavor of X display active.
