kichikuou	da5ac4a26c	Support OpenGL ES 3.0 This adds `USE_GLES` compile-time flag. If it's defined, gfx_init() requests an OpenGL ES >=3.0 context. This also makes the following changes to make it work with OpenGL ES: - The USE_GLES flag also switches shader's #version directive, which is now provided separately from the .glsl file. - Implicit conversion between int and float is not supported in GLSL ES. - Use GL_RGB in gfx_copy_main_surface. Because main_surface is in GL_RGB format, using GL_RGBA generates GL_INVALID_OPERATION in OpenGL ES.	2021-06-20 17:12:35 +09:00

Support OpenGL ES 3.0

This adds `USE_GLES` compile-time flag. If it's defined, gfx_init()
requests an OpenGL ES >=3.0 context.

This also makes the following changes to make it work with OpenGL ES:

- The USE_GLES flag also switches shader's #version directive, which is
  now provided separately from the .glsl file.
- Implicit conversion between int and float is not supported in GLSL ES.
- Use GL_RGB in gfx_copy_main_surface. Because main_surface is in GL_RGB
  format, using GL_RGBA generates GL_INVALID_OPERATION in OpenGL ES.

Use OpenGL instead of SDL's 2D graphics API

This will be necessary for supporting 3D games in the future (Rance VI,
GALZOO, etc.).
