Misaligned pointer access in the command list.

[prideout]

This is minor but it might be nice to fix the address sanitizer output that look like this:

runtime error: member access within misaligned address 0x000112e73f44 for type 'mu_Command', which requires 8 byte alignment

Thankfully this seems really to fix: 1) Add an expect(size % 8 == 0) at the top of mu_push_command 2) Add 4 bytes of padding to mu_RectCommand 3) Change mu_draw_text to do:

    int aligned_size = len + 8 - (len % 8);
    cmd = mu_push_command(ctx, MU_COMMAND_TEXT, sizeof(mu_TextCommand) + aligned_size);

Same issue here.

I fixed it by changing mu_push_command to this:

mu_Command* mu_push_command(mu_Context *ctx, int type, int size) {
  mu_Command *cmd = (mu_Command*) (ctx->command_list.items + ctx->command_list.idx);
  const int al = sizeof(void*) - 1;
  size = (size + al) & ~al;
  expect(size % sizeof(void*) == 0);
  expect(ctx->command_list.idx + size < MU_COMMANDLIST_SIZE);
  cmd->base.type = type;
  cmd->base.size = size;
  ctx->command_list.idx += size;
  return cmd;
}
