Support OpenGL ES #22

Open rzr opened 3 years ago

rzr commented 3 years ago

This will help to support more devices like SBC ARM boards.

Note that some drivers are supporting both API GL desktop / ES (like VC4 from Raspberry PI)

Hi for the record I have succesfully tested @caramelli change (<3):

https://github.com/adoptware/pinball/pull/23

Display shows up on Pi on ubuntu-21.04 aarch64 (beta) using "pincab" profile,

with SDL master (with opengles1 enabled):

it's a progress I'll merge this, unless anyone object i?

For the record

May I keep this ticket open for any OpenGLES related efforts (ie: GLES2)

Anyway, desktop GL API is way faster as shown in last clip:
