[Mesa-dev] [PATCH] gallium/hud: add a simple HUD view that only draws text
Marek Olšák
maraeo at gmail.com
Thu Apr 5 00:04:39 UTC 2018
From: Marek Olšák <marek.olsak at amd.com>
Add this prefix to the env var: "simple," For example:
GALLIUM_HUD=simple,fps
The X coordinates are the same, but the Y coordinates are different, because
there is only text.
'+' happens to behave the same as "\n".
',' happens to behave the same as "\n\n".
