While trying to make raylib work in WASI and OpenGL ES, i figured out that my OpenGL ES driver does not supports quads draw mode. But disabling SUPPORT_QUADS_DRAW_MODE leads to following bugs:
I tried a few examples and managed to fix RL_QUADS bug for them (that was hard due to way debugger in wasmtime works). Fixes are straightforward, but it is likely that RL_QUADS is still used in some raylib modules and examples. BTW there is an alternative way to solve this problem: emulating RL_QUADS using triangles and pushing 2 additional vertices every 4th call of rlVertex3f. I guess it worth investigating.
Honestly i don't know how textures worked before, but in my case i had to make raylib restore texture(which is usually set by rlSetTexture before rlBegin call) when draw mode switches (inspired by #2018)
