for compatibility with mobile GLES drivers.

3c1cd2873b WebGL1 some changes 
glRenderBufferStorage doesn't accept the _DEPTH_COMPONENT24_OES so I changed it to GL_DEPTH_COMPONENT16
https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/renderbufferStorage
https://www.khronos.org/registry/webgl/extensions/rejected/OES_depth24/

Enabled ext_shader_texture_lod extension. I guess it does the same like the GL_ARB_shader_texture_lod extension, but in WebGL1
https://www.khronos.org/registry/webgl/extensions/EXT_shader_texture_lod/

And last WebGL1 doesn't allow indexes not constant, so I changed it into a loop reading this:

e7e9a7cc6c webgl1 doesn't like backslashes in #define 
According to
https://www.khronos.org/registry/OpenGL/specs/es/2.0/GLSL_ES_Specification_1.00.pdf
, backslashes aren't necessary supported as line continuation characters
in preprocessor directives

57416bfbce GLES2: Define 'lowp' for OpenGL 2.1 
Precision qualifiers are only used on OpenGL ES 2.0 and 3.0,
and while OpenGL 3.3 defines them for compatibility (but without
practical effect), they're missing from OpenGL 2.1, so we define
them to prevent compilation errors.

Fixes #24521.
