fix: Dejar que SDL elija OpenGL automáticamente en Linux

Browse Source 
- Windows: opengl + 3.3 Core Profile explícito
- Linux: opengl sin atributos, SDL elige:
  * Desktop 3.3 en PC con GPU normal
  * ES 3.0 en RPi automáticamente

Resuelve problema de colores invertidos (azul->naranja) causado
por forzar opengles2.
